All hardware should appear on the Windows 2000 Hardware Compatibility List (HCL) (KB# Q142865)

Installing from CD-ROM:

	Setup disks are not required if your CD-ROM is bootable or you are upgrading a previous version of Windows.
	To make boot floppies, type makeboot a: in the \bootdisk directory of your W2K CD. Creates set of four 1.44 MB boot floppies. (KB# Q197063)
	If installing using a MS-DOS or Win95/98 boot floppy, run winnt.exe from the i/386 to begin Windows 2000 setup.
	Setup will not prompt the user to specify the name of an installation folder unless you are performing an unattended installation or using winnt32 to perform a clean installation. (KB# Q222939)

Installing over a Network:

	Create a distribution server which has a file share containing the contents of the /i386 directory from the Windows 2000 CD-ROM.
	685 MB minimum plus 100 - 200 MB free hard drive space to hold temporary files during installation.
	Install a network client on the target computer or use a boot floppy that includes a network client (KB# Q142857). Run winnt.exe from file share on distribution server if installing a new operating system or winnt32.exe if upgrading a previous version of Windows.
	Clean installation is now possible with Windows 2000. NT 4 required a pre-existing FAT partition.

Command line switches for winnt.exe:

Unattended installations:

1. Provide Defaults - Administrator supplies default answers and user only has to accept defaults or make changes where necessary.
2. Fully Automated - Mainly used for Win2000 Professional desktop installs. User just has to sit on their hands and watch.
3. Hide Pages - Users can only interact with setup where Administrator did not provide default information. Display of all other dialogs is supressed.
4. Read Only - Similar to above, but will display information to user without allowing interaction to pages where Administrator has provided default information.
5. GUI Attended - Only used for automating the second stage of setup. All other stages require manual input.

	Unattended installations rely on an answer file to provide information during setup process that is usually provided through manual user input. (KB# Q183245)
	Answer files can be created manually using a text editor or by using the Setup Manager Wizard (SMW) (found in the Windows 2000 Resource Kit Deployment Tools).
	SMW allows for creation of a shared Distribution Folder and OEM Branding
	If you had a CD in drive D: and an unattended installation answer file named salesans.txt in C:\, you could start your install with this command: D:\i386\winnt32 /s:d:\i386 /unattend:c:\salesans.txt (KB# Q216258)
	When doing a CD-based install of W2K Pro and are booting from CD, name your answer file WINNT.SIF and make sure it is on a floppy disk in your floppy drive. The serial # for the CD should be entered into the .SIF file to avoid a need for manual user input during the install.
	There are five levels of user interaction during unattended installs:

Deploy Windows 2000 by using Remote Installation Services (RIS):

	DHCP Server Service
	Active Directory
	DNS Server Service
	At least 2 GB of disk space. Hard disk must have at least two partitions, one for the Operating System and one for the images. Image partition must be formatted with NTFS. RIS packages cannot be installed on either the system or boot partitions. Also cannot be on an EFS volume or DFS shared folder.

	Install Remote Installation Services using Control Panel > Add/Remove Programs > Windows Components.
	Start the RIS Setup Wizard by running risetup. Specify the Remote Installation Folder Location. For Initial Settings, choose Do not respond to any client requests (default setting - RIS Server must be authorized first). Specify the location of the W2K Professional source files for building the initial CD-based image. Designate a folder inside the RIS folder where the CD image will be stored. Provide a friendly text name for the CD-based image.
	Setup Wizard creates the folder structure, copies needed source files to the server, creates the initial CD-based W2K Professional image in its designated folder along with the default answer file (Ristandard.sif), and starts the RIS services on the server.
	Server must now be authorized. Open Administrative Tools > DHCP. Right-click DHCP in the console tree and choose Manage authorized servers. When dialog appears, click Authorize and enter name or IP of the RIS server (user must be a member of the Enterprise Admins group to do this).
	You may now configure your RIS Server to respond to client requests.
	Assign users/groups that will be performing RIS Installations permissions to Create Computer Objects in Active Directory.
	The Client Computer Naming Format is defined through Active Directory Users & Computers. Right-click the RIS Server and click Properties > Remote Install > Advanced Settings > New Clients. Choose a pre-defined format or create a custom one. Variables are: %Username (user logon name), %First (user first name), %Last (user last name), %# (incremental number), %MAC (NIC hardware address) (KB# Q244964)
	Associate an answer file (.SIF) with your image.

	Procure a Source Computer and install Windows 2000 Professional. Configure all components and settings for your desired client configuration keeping everything on a single partition (RIPrep Wizard can only image a single partition).
	Install your applications and configure them. Do not install unnecessary applications - remember that RIS requires Active Directory which can be used to publish or assign software as needed using Group Policy.
	As you created and configured the system using the Administrator profile, you will need to copy your configuration to the Default User profile so that your custom settings will not be lost.
	To launch the RIPrep Wizard, click Start > Run and type the following into the Open box: \\RISServerName\reminst\admin\i386\riprep.exe. Provide the name of the RIS Server where the image will be stored, the folder that will hold the image and a friendly text description.

	Client machine must meet minimum hardware requirements for Windows 2000 Professional and must use the same Hardware Abstraction Layer (HAL).
	Must have a network adapter that meets the Pre-boot Execution Environment standard (PXE) version 99c and higher (there is a confirmed problem with v99j - KB# Q244454) or a 3 1/2" floppy drive and PCI network adapter supported by the RIS Startup Disk utility's list of supported adaptors. (KB# Q244036 & Q246184)

	If computer displays a BootP message but doesn't display the DHCP message, check to see if it can obtain an IP address. If it cannot, make sure a DHCP server is online, is authorized, has a valid IP address scope and that the DHCP packets are being routed (you may need to install a DHCP relay agent if your DHCP server is located on a different network segment than the RIS client - KB# Q174765)
	Computer displays the DHCP message but does not display the Boot Information Negotiations Layer (BINL) message. Make sure the RIS server is online and authorized and that DHCP packets are being routed. (KB# Q235979)
	BINL message is displayed but system is unable to connect to RIS server. Try restarting the NetPC Boot Service Manager (BINLSVC) on the RIS Server.
	If the Client cannot connect to RIS Server using the Startup disk check to make sure you used the right network adapter driver in rbfg.exe.
	If the installation options you expected are not available, there may be Group Policy conflicts. Check to make sure another Group Policy Object did not take precedence over your own.

	You cannot create RIPrep images on a server unless it already has an existing CD-based image.
	The Remote Boot Floppy Generator utility (rbfg.exe) only works on Windows 2000 systems (KB# Q246618). To create boot floppies, click Start > Run and then type: \\RISServerName\reminst\admin\i386\rbfg.exe and click OK
	The answer file (.SIF) supports the new [RemoteInstall] section. Setting the repartition parameter to yes causes the install to delete all partitions on the client computer and reformat the drive with one NTFS partition.
	Pre-staging images using the GUID of PXE-based workstations prevents unauthorized users from illegally installing Windows 2000 onto their systems.
	The MAC address of the network adapter can be entered into the GUID field and padded with zeros.

Working with SYSDIFF:

	Used for installing applications, usually in conjuction with an unattended installation. SYSDIFF allows you to take a snapshot of your machine's original state, install applications, and then package all of these changes into a single file which can be applied to other machines.
	Install your baseline system first. Then take a snapshot of it before installing any applications. Syntax is: sysdiff /snap snap_file
	Next install desired applications on target system. Use the SYSDIFF tool to create a difference file. Syntax is: sysdiff /diff snap_file diff_file
	You can now apply your difference file to the target system(s). Syntax is: sysdif /apply \\setupserver\w2k\diff_file

System preparation tool (SYSPREP.EXE): (KB# Q240126)

	Removes the unique elements of a fully installed computer system so that it can be duplicated using imaging software such as Ghost or Drive Image Pro. Avoids the NT4 problem of duplicated SIDS , computer names etc. Installers can use sysprep to provide and answer file for "imaged" installations.
	Must be extracted from DEPLOY.CAB in the \support\tools folder on the Windows 2000 Professional CD-ROM.
	Adds a mini-setup wizard to the image file which is run the first time the computer it is applied to is started. Guides user through re-entering user specific data. This process can be automated by providing a script file. (KB# Q196667)
	Use Setup Manager Wizard (SMW) to create a SYSPREP.INF file. SMW creates a SYSPREP folder in the root of the drive image and places sysprep.inf in this folder. The mini-setup wizard checks for this file when it runs.
	Specifying a CMDLINES.TXT file in your SYSPREP.INF file allows an administrator to run commands or programs during the mini-Setup portion of SYSPREP. (KB# Q238955)
	Available switches for sysprep.exe are: /quiet (runs without user interaction), /pnp (forces Setup to detect PnP devices), /reboot (restarts computer), and /nosidgen (will not regenerate SID on target computer).

Upgrading from a previous version: (KB# Q232039)

	Run winnt32.exe to upgrade from a previous version of Windows. (KB# Q199349)
	Windows 2000 will upgrade and preserve settings from the following operating systems: Windows 95 and 98 (all versions), Windows NT Workstation 3.51 and 4.0, and Windows NT 3.1 or 3.5 (must be upgraded to NT 3.51 or 4.0 first, then Professional).
	Upgrade installations from a network file share are not supported in Windows 2000 (this *can* be done, but only by using SMS). You must either do a CD-based upgrade or perform a clean installation of Windows 2000 and re-install needed applications.
	Because of registry and program differences between Win95/98 and 2000, upgrade packs (or migration DLLs) might be needed. Setup checks for these in the \i386\Win9xmig folder on the Windows 2000 CD-ROM or in a user specified location. (KB# Q231418)
	Run winnt32 /checkupgradeonly to check for compatible hardware and software. Generates a report indicating which system components are Windows 2000 compatible. Same as running the chkupgrd.exe utility from Microsoft's site.
	All operating system files associated with Windows 95/98 will be deleted after an upgrade. (KB# Q228986)

Troubleshooting failed installations:

Choosing a file system:

	NTFS provides optimum security and reliability through it's ability to lock down individual files and folders on a user by user basis. Advanced features such as disk compression, disk quotas and encryption make it the file system recommended by 9 out of 10 MCSEs. (KB# Q244600)
	FAT and FAT32 are only used for dual-booting between Windows 2000 and another operating system (like DOS 6.22, Win 3.1 or Win 95/98). (KB# Q184006)
	Existing NT 4.0 NTFS system parition will be upgraded to Windows 2000 NTFS automatically. If you wish to dual-boot between NT4.0 and 2000 you must first install Service Pack 4 on the NT4.0 machine. This will allow it to read the upgraded NTFS partition, but advanced features such as EFS and Disk Quotas will be disabled. (KB# Q197056 & Q184299)
	Use convert.exe to convert a FAT or FAT32 file system to NTFS. NTFS partitions cannot be converted to FAT or FAT32 - the partition must be deleted and recreated as FAT or FAT32 (KB# Q156560 & Q214579)
	You cannot convert a FAT partition to FAT32 using convert.exe. (KB# Q197627)

NTFS file and folder permissions: (KB#S Q183090, Q244600)

Miscellaneous:

	NTFS in Windows 2000 (version 5) features enhancements not found in Windows NT 4.0 version 4). Reparse Points, Encrypting File System (EFS), Disk Quotas, Volume Mount Points, SID Searching, Bulk ACL Checking, and Sparse File Support. (KB# Q183090)
	Volume Mount Points allow new volumes to be added to the file system without needing to assign a drive letter to it. Instead of mounting a CD-ROM as drive E:, it can be mounted and accessed under an existing drive (e.g., C:\CD-ROM). As Volume Mount Points are based on Reparse Points, they are only available under NTFS5 using Dynamic Volumes.
	NTFS4 stored ACLs on each file. With bulk ACL checking, NTFS5 uses unique ACLs only once even if ten objects share it. NTFS can also perform a volume wide scan for files using the owner's SID (SID Searching). Both functions require installation of the Indexing Service.
	Sparse File Support prevents files containing large consecutive areas of zero bits from being allocated corresponding physical space on the drive and improves system performance.
	NTFS partitions can be defragmented in Windows 2000 (as can FAT and FAT32 partitions). Use Start > Programs > Accessories > System Tools > Disk Defragmenter.
	Local security access can be set on a NTFS volume.
	Files moved from an NTFS partition to a FAT partition do not retain their attributes or security descriptors, but will retain their long filenames.
	Permissions are cumulative, except for No Access, which overrides anything.
	File permissions override the permissions of its parent folder.
	Anytime a new file is created, the file will inherit permissions from the target folder.
	The cacls.exe utility is used to modify NTFS volume permissions. (KB# Q237701)

Windows File Protection Feature (WFP): (KB# Q222193)

	New to Windows 2000 - prevents the replacement of certain monitored system files (important DLLs and EXEs in the %systemroot%\system32 directory).
	Uses file signatures and code signing to verify if protected system files are the Microsoft versions.
	WFP does not generate signatures of any type.
	Critical DLLs are restored from the %systemroot%\system32\dllcache directory. Default maximum size for Professional is 50MB. This can be increased by editing the Registry. (KB# Q229656)

Local and network print devices:

	Windows 2000 Professional supports the following printer ports: Line Printer (LPT), COM, USB, IEEE 1394, and network attached devices.
	Print services can only be provided for Windows and UNIX clients on Windows 2000 Professional (KB# Q124734)- Windows 2000 Server is required to support Apple and Novell clients.
	Windows 2000 Professional automatically downloads the printer drivers for clients running Win2000, WinNT 4, WinNT 3.51 and Windows 95/98. (KB# Q142667)
	Internet Printing is a new feature in Windows 2000. You have the option of entering the URL where your printer is located. The print server must be a Windows 2000 Server running Internet Information Server or a Windows 2000 Professional system running Personal Web Server - all shared printers can be viewed at: http://servername/printers
	Print Pooling allows two or more identical printers to be installed as one logical printer.
	Print Priority is set by creating multiple logical printers for one physical printer and assigning different priorities to each. Priority ranges from 1, the lowest (default) to 99, the highest.
	Enabling "Availability" option allows Administrator to specify the hours the printer is available.
	Use Separater Pages to separate print jobs at a shared printer. A template for the separater page can be created and saved in the %systemroot%\system32 directory with a .SEP file extension. (KB# Q102712)
	You can select Restart in the printer's menu to reprint a document. This is useful when a document is printing and the printer jams. Resume can be selected to start printing where you left off.
	You can change the directory containing the print spooler in the advanced server properties for the printer. (KB# Q123747)
	To remedy a stalled spooler, you will need to stop and restart the spooler services in the Services applet in Administrative Tools in the Control Panel. (KB# Q240683 &
	Use the fixprnsv.exe command-line utility to resolve printer incompatibility issues. (KB# Q247196)

Managing file systems: (KB# Q222189)

There are three volume types:

	Simple volume - contains space from a single disk
	Spanned volume - contains space from multiple disks (maximum of 32). First fills one volume before going to the next. If a volume in a spanned set fails, all data in the spanned volume set is lost. Performance is degraded as disks in spanned volume set are read sequentially.
	Striped set- contains free space from multiple disks (maximum of 32) in one logical drive. Increases performance by reading/writing data from all disks at the same rate. If a disk in a stripe set fails, all data is lost.

Dynamic Volume States:

Dynamic Volume Limitations:

	Cannot be directly accessed by DOS, Win95/98 or any versions of Windows NT if you are dual-booting as they do not use the traditional disk organization scheme of partitions and logical volumes. MBR on dynamic disks contains a pointer to disk configuration data stored in the last 1 MB of space at the end of the disk. (KB# Q197738)
	Dynamic volumes which were upgraded from basic disk partitons cannot be extended, especially the system volume which holds hardware-specific files required to start Windows 2000 and the boot volume. Volumes created after the disk was upgraded to dynamic can be extended. (KB# Q222188)
	When installing Windows 2000, if a dynamic volume is created from unallocated space on a dynamic disk, Windows 2000 cannot be installed on that volume. (KB# Q216341)
	Not supported on portable computers or removable media. (KB# Q232463)
	A boot disk that has been converted from basic to dynamic cannot be converted back to basic. (KB# Q217226)

Translation of terms between Basic and Dynamic Disks:

When using the Disk Management Snap-in Tool:

	Whenever you add a new disk in a computer it is added as Basic Storage
	Every time you remove or add a new disk to your computer you must choose Rescan Disks
	Disks that have been removed from another computer will appear labeled as Foreign. Choose "Import Foreign Disk" and a wizard appears to provide instructions.
	For multiple disks removed from another computer, they will appear as a group. Right-click on any of the disks and choose "Add Disk".
	Disks can be upgraded from Basic to Dynamic storage at any time but must contain at least 1 MB of unallocated space for the upgrade to work.

Implementing, Managing, and Troubleshooting Hardware Devices and Drivers: (KB# Q199276)

Miscellaneous:

	Windows 2000 now fully supports Plug and Play. (KB# Q133159)
	Use the "System Information" snap-in to view configuration information about your computer (or create a custom console focused on another computer - powerful tool!!).
	"Hardware Resources" under System Information allows you to view Conflicts/Sharing, DMAs, IRQs, Forced Hardware, I/O and Memory.
	Hardware is added and removed using the "Add/Remove Hardware" applet in the Control Panel (can also be accessed from Control Panel > System > Hardware > Hardware Wizard).
	All currently installed hardware is managed through the "Device Manager" snap-in.
	To troubleshoot a device using Device Manager, click the "Troubleshoot" button on the General tab.

Disk devices:

	Managed through "Computer Management" under Control Panel > Administrative tools or by creating a custom console and adding the "Disk Management" snap-in. Choosing the "Computer Management" snap-in for your custom console gives you the following tools: Disk Management, Disk Defragmenter, Logical Drives and Removable Storage. There is a separate snap-in for each of these tools except for Logical Drives.
	Using Disk Management, you can create, delete, and format partitions as FAT, FAT32 and NTFS. Can also be used to change volume labels, reassign drive letters, check drives for errors and backup drives.
	Defragment drives by using "Disk Defragmenter" under "Computer Management" or add the "Disk Defragmenter" snap-in to your own custom console. (KB# Q227463)
	Removable media are managed through the "Removable Media" snap-in.

Display devices:

	Desktop display properties (software settings) are managed through the Display applet in Control Panel.
	Display adapters are installed, removed and have their drivers updated through "Display Adapters" under the Device Manager.
	Monitors are installed, removed, and have their drivers updated through "Monitors" under the Device Manager.
	Windows 2000 Professional supports multiple monitors running concurrently.

Mobile computer hardware:

	PCMCIA (PC Card) adapters, USB ports, IEEE 1394 (FireWire), and Infrared devices now supported. These are managed through Device Manager.
	Hot (computer is fully powered) and warm (computer is in suspend mode) docking and undocking are now fully supported for computers with a PnP BIOS.
	Support is provided for Advanced Power Management (APM) and Advanced Configuration and Power Interface (ACPI). (KB# Q242495)
	Hibernation (complete power down while maintaining state of open programs and connected hardware) and Suspend (deep sleep with some power) modes are now supported, extending battery life.
	When a PC Card, USB or Infrared device is installed, Windows 2000 will automatically recognize and configure it (if it meets PnP specifications). If Windows does not have an entry in its driver base for the new hardware, you will be prompted to supply one.
	Equipping mobile computers with SmartCards and Encrypting File System decreases the likelihood of confidential corporate data being compromised if the computer is stolen or lost.
	Use hardware profiles for mobile computers. Accessed through Control Panel > System applet > Hardware tab > Hardware Profiles. Multiple profiles can be created and designated as a docked or undocked portable computer.

Input and output (I/O) devices:

	Keyboards are installed under "Keyboards" in Device Manager.
	Mice, graphics tablets and other pointing devices are installed under "Mice and other pointing devices" in Device Manager.
	Troubleshoot I/O resource conflicts using the "System Information" snap-in. Look under Hardware Resources > I/O for a list of memory ranges in use.

Updating drivers:

	Drivers are updated using Device Manager. Highlight the device, right-click and choose Properties. A properties dialog appears. Choose the Drivers tab and then the Update Driver... button.
	Microsoft recommends using Microsoft digitally signed drivers whenever possible. (KB# Q244617)
	The Driver.cab cabinet file on the Windows 2000 CD contains all of the drivers the OS ships with. Whenever a driver is updated, W2K looks here first. The location of this file is stored in a registry key and can be changed: HKLM\Software\Windows\CurrentVersion\Setup\DriverCachePath  (KB# Q230644)
	The Driver Verifier is used to troubleshoot and isolate driver problems. It must be enabled through changing a Registry setting. The Driver Verifier Manager, verifier.exe, provides a command-line interface for working with Driver Verifier. (KB# Q244617)

Managing/configuring multiple CPUs:

	Adding a processor to your system to improve performance is called scaling. Typically done for CPU intensive applications such as CAD and graphics rendering.
	Windows 2000 Professional supports a maximum of two CPUs. If you need more consider using Windows 2000 Server (up to 4 CPUs), Advanced Server (up to 8 CPUs) and Datacentre Server (maximum of 32 CPUs).
	Windows 2000 supports Symetric Multiprocessing (SMP). Processor affinity is also supported. Asymetric Multiprocessing (ASMP) is not supported.
	Upgrading to multiple CPUs might increase the load on other system resources.
	Update your Windows driver to convert your system from a single to multiple CPUs. This is done through Device Manager > Computer > Update Driver. (KB# Q234558)

Install and manage network adapters:

	Adapters are installed using the Add/Remove Hardware applet in Control Panel
	Change the binding order of protocols and the Provider order using Advanced Settings under the Advanced menu of the Network and Dial-up Connections window (accessed by right-clicking on My Network Places icon)
	Each network adapter has an icon in Network and Dial-up connection. Right click on the icon to set it's properties, install protocols, change addresses, etc.

Troubleshooting the boot process:

multi(0)disk(0)rdisk(0)partition(1). These are the lowest numbers that an ARC path can have.

BOOT.INI switches: (KB# Q239780)

	/basevideo - boots using standard VGA driver
	/fastdetect=[comx,y,z] - disables serial mouse detection or all COM ports if port not specified. Included by default
	/maxmem:n - specifies amount of RAM used - use when a memory chip may be bad
	/noguiboot - boots Windows without displaying graphical startup screen
	/sos - displays device driver names as they load
	/bootlog - enable boot logging
	/safeboot:minimal - boot in safe mode
	/safeboot:minimal(alternateshell) - safe mode with command prompt
	/safeboot:network - safe mode with networking support (KB# Q236346)

Booting in Safe Mode: (KB# Q202485)

	Enter safe mode by pressing F8 during operating system selection phase
	Safe mode loads basic files/drivers, VGA monitor, keyboard, mouse, mass storage and default system services. Networking is not started in safe mode. (KB# Q199175)
	Enable Boot Logging - logs loading of drivers and services to ntbtlog.txt in the windir folder
	Enable VGA Mode - boots Windows with VGA driver
	Last Known Good Configuration - uses registry info from previous boot. Used to recover from botched driver installs and registry changes.
	Recovery Console - only appears if it was installed using winnt32 /cmdcons or specified in the unattended setup file.
	Directory Services Restore Mode - only in Server for restoring Active Directory information to domain controllers, not applicable to Win2000 Professional.
	Debugging Mode - again, only in Server
	Boot Normally - lets you boot, uh, normally. ;-)

Windows 2000 Control Sets: (KB# Q142033)

	Found under HKEY_LOCAL_MACHINE\System\Select - has four entries
	Current- CurrentControlSet. Any changes made to the registry modify information in CurrentControlSet
	Default - control set to be used next time Windows 2000 starts. Default and current contain the same control set number
	Failed - control set marked as failed when the computer was last started using the LastKnownGood control set
	LastKnownGood - after a successful logon, the Clone control set is copied here

Running the Recovery Console: (KB# Q229716)

	Insert Windows 2000 CD into drive, change to i386 folder and run winnt32 /cmdcons (KB# Q216417)
	After it is installed, it can be selected from the "Please Select Operating System to Start" menu
	When starting Recovery Console, you must log on as Administrator. (KB# Q239803)
	Can also be run from Windows 2000 Setup, repair option.
	Allows you to boot to a "DOS Prompt" when your file system is formatted with NTFS.
	Looks like DOS, but is very limited. By default, you can copy from removable media to hard disk, but not vice versa - console can't be used to copy files to other media (KB# Q240831). As well, by default, the wildcards in the copy command don't work (KB# Q235364). You can't read or list files on any partition except for system partition.
	Can be used to disable services that prevent Windows from booting properly (KB# Q244905)

	Accessed through Control Panel > System applet > Advanced tab > Startup and Recovery
	Memory dumps are always saved with the filename memory.dmp (KB# Q192463)
	Small memory dump needs 64K of space. Found in %systemroot%\minidump
	A paging file must be on the system partition and the pagefile itself at least 1 MB larger than the amount of RAM installed for Write debugging information option to work
	Use dumpchk.exe to examine contents of memory.dmp (KB# Q156280)

Windows Report Tool: (KB# Q188104)

	Used to gather information from your computer to assist support providers in troubleshooting issues. Reports are composed in Windows 98 and Windows 2000 and then uploaded to a server provided by the support provider using HTTP protocol.
	Reports are stored in a compressed .CAB format and include a Microsoft System Information (.NFO) file.
	The report generated by Windows Report Tool (winrep.exe) includes a snapshot of complete system software and hardware settings. Useful for diagnosing software and hardware resource conflicts.

Emergency Repair Disk:

	Windows NT 4 users - the RDISK utility is gone, ERDs are now made exclusively with the backup utility. It has been changed from a repair disk to a boot disk which lets you run repair tools on the CD (KB# Q216337)
	To make an ERD, run ntbackup, choose Emergency Repair Disk and insert a blank formatted floppy into the A: drive. You will also have the option to copy registry files to the repair directory - it's a good idea to do so (%systemroot%\repair\regback). Also use backup to copy these registry files to a tape or Zip disk. (KB# Q231777)
	ERD contains the following files: autoexec.nt, config.nt and setup.log

Monitoring and Optmizing System Performance and Reliability:

Configuring Driver Signing: (KB# Q236029)

	Open System applet in Control Panel and click Hardware tab. Then in the Device Manager box, click Driver Signing to display options:
	Ignore - Install all files, regardless of file signature
	Warn- Display a message before installing an unsigned file
	Block- Prevent installation of unsigned files
	The Apply Setting As System Default checkbox is only accessible to Administrators

Using System File Checker (sfc.exe): (KB# Q222471)

	/scannow - scans all protected system files immediately
	/scanonce - scans all protected system files at next startup
	/scanboot- scans all protected system files at every restart
	/cancel- cancels all pending scans
	/quiet - replaces incorrect files without prompting
	/enable - sets Windows File Protection back to defaults
	/purgecache - purges file cache and forces immediate rescan
	/cachesize=x- sets file cache size

Windows Signature Verification (sigverif.exe):

	running sigverif launches File Signature Verification
	checks system files by default, but non-system files can also be checked
	saves search results to Sigverif.txt

Task scheduler: (KB# Q235536 & Q226262)

	used to automate events such as batch files, scripts and system backups
	tasks are stored in the Scheduled Tasks folder in Control Panel
	running task with a user name and password allows an account with the required rights to perform the task instead of an administrative account
	set security for a task by group or user

Using offline files:

Share a folder and set it's caching to make it available offline - three types of caching:

	manual caching for documents - default setting. Users must specify which docs they want available when working offline
	automatic caching for documents - all files opened by a user are cached on his local hard disk for offline use - older versions on users machine automatically replaced by newer versions from the file share when they exist
	automatic caching for programs -same as above, but for programs

When synchronizing, if you have edited an offline file and another user has also edited the same file you will be prompted to keep and rename your copy, overwrite your copy with the network version, or to overwrite the network version and lose the other user's changes (a wise SysAdmin will give only a few key people write access to this folder or everyone's work will get messed up).

Performance Console: (KB# Q146005)

	Important objects are cache (file system cache used to buffer physical device data), memory (physical and virtual/paged memory on system), physicaldisk (monitors hard disk as a whole), logicaldisk (logical drives, stripe sets and spanned volumes), and processor (monitors CPU load)
	Processor - % Processor Time counter measure's time CPU spends executing a non-idle thread. If it is continually at or above 80%, CPU upgrade is recommended
	Processor -  Processor Queue Length - more than 2 threads in queue indicates CPU is a bottleneck for system performance
	Processor - % CPU DPC Time (deferred procedure call) measures software interrupts.
	Processor - % CPU Interrupts/Sec measures hardware interrupts. If processor time exceeds 90% and interrupts/time exceeds 15%, check for a poorly written driver (bad drivers can generate excessive interrupts) or upgrade CPU.
	Logical disk - Disk Queue Length - If averaging more than 2, drive access is a bottleneck. Upgrade disk, hard drive controller, or implement stripe set
	Physical disk - Disk Queue Length - same as above
	Physical disk - % Disk Time- If above 90%, move data/pagefile to another drive or upgrade drive
	Memory - Pages/sec - more than 20 pages per second is a lot of paging - add more RAM
	Memory - Commited bytes - should be less than amount of RAM in computer
	diskperf command for activating disk counters has been modified in Windows 2000, physical disk counters are now enabled by default, but you will have to type diskperf -yv at a command prompt to enable logical disk counters for logical drives or storage volumes. (KB# Q253251

Performance Alerts and Logs: (KB# Q244640)

	Alert logs are like trace logs, but they only log an event, send a message or run a program when a user-defined threshold has been exceeded
	Counter logs record data from local/remote systems on hardware usage and system service activity
	Trace logs are event driven and record monitored data such as disk I/O or page faults
	By default, log files are stored in the \Perflogs folder in the system's boot partition
	Save logs in CSV (comma separated value) or TSV (tab separated value) format for import into programs like Excel
	CSV and TSV must be written all at once, they do not support logs that stop and start. Use Binary (.BLG) for logging that is written intermittantly
	Logging is used to create a baseline for future reference

Virtual memory/Paging file:

	Recommended minimum paging file size is 1.5 times the amount of RAM installed. A system with 64 MB should have a 96 MB page file. Maximum page file size should not exceed 2.5 times the amount of RAM installed
	Set through Control Panel > System applet > Advanced tab > Performance Options > Change
	The most efficient paging file is spread across several drives, but is not on the system or boot partitions. (KB# Q123747)
	Maximum registry size can also be changed through the Virtual Memory dialog box

Hardware profiles:

	Created to store different sets of configuration settings to meet a users different needs (usually used with portables) such as whether a computer is docked or undocked.
	User selects the desired profile at Windows 2000 startup
	Profiles are created through Control Panel > System applet > Hardware tab > Hardware Profiles
	Devices are enabled and disabled in particular profiles through their properties in the Device Manager snap-in

Data recovery:

	Windows 2000 Backup is launched through Control Panel > System applet > Backup or by running ntbackup from the Start menu (KB# Q241007)
	Users can back up their own files and files they have read, execute, modify, or full control permission for
	Users can restore files they have write, modify or full control permission for
	Administrators and Backup Operators can backup and restore all files regardless of permissions

Database that stores Windows 2000 configuration information for all installed software, hardware and users in a hierarchical structure. Consists of five main subtrees:

	HKEY_CLASSES_ROOT - holds software configuration data, file associations and object linking and embedding (OLE) data
	HKEY_CURRENT_CONFIG - holds data on active hardware profile extracted from SOFTWARE and SYSTEM hives
	HKEY_CURRENT_USER - contains data about current user extracted from HKEY_USERS and additional info pulled down from Windows authentication
	HKEY_LOCAL_MACHINE - contains all local computer hardware, software, device driver and startup information. Remains constant regardless of the user
	HKEY_USERS - holds data for user identities and environments, custom settings, etc

The Registry Editor (Regedt32.exe) has a read-only mode, a security menu, and supports the REG_EXPAND_SZ and REG_MULTI_SZ data types. Regedit.exe (another registry editing tool installed by Windows 2000) does not. Registry Editor automatically saves changes as they are made.

Secondary Logon Service (Run As): (KB# Q225035)

	Similar to the SU (Super User) command in UNIX
	Used to test setting using a particular user account while logged in with a different account
	Select the application icon using a single left-click, hold down the Shift key and right-click the icon. When the pop-up menu appears, click Run As. This brings up a dialog box titled "Run program as other user" - enter your credentials and click OK

Configuring and Troubleshooting the Desktop Environment:

User profiles:

	Is a collection of data and folders that store the user's desktop environment and application settings along with personal data.
	When a user logs onto a client computer running W2K Pro, he/she always receives his/her individualized desktop settings and all of their network connections regardless of how many users share the same computer.
	A user can change their user profile by changing their desktop settings - when they log off, Windows 2000 incorporates the changes into their user profile.
	Setting a profile as mandatory forces Windows to discard any changes made during the session so the next time the user logs on, the session remains unchanged from their last login.
	User profiles are stored in the %systemroot%\Documents and Settings\%username% folder in a fresh install of W2K. When upgraded from NT4, they are stored in %systemroot%\Profiles\%username%
	Roaming profiles are used in Windows 2000 domains for users who move from one computer to another but require a consistent desktop environment.

Multiple languages and locations:

Deploy software by using Group Policy:

	Replaces setup.exe. Windows Installer packages are recognized by their .MSI file extension.
	Integrates software installation into Windows 2000 so that it is now centrally controlled, distributed, and managed from a central-point.
	The software life cycle consists of four phases, Preparation, Deployment, Maintenance, and Removal.

Maintain software by using Group Policy:

	Software package is installed on a Windows 2000 Server in a shared directory. A Group Policy Object (GPO) is created. Behavior filters are set in the GPO to determine who gets the software. Then the package is added to the GPO under User Configuration > Software Settings > Software Installation (this is done on the server). You are prompted for a publishing method - choose it and say OK.
	Set up Application Categories in Group Policy > computer or user config > Software Settings > Software Installation (right-click) > Properties > Categories > Add. Creating logical categories helps users locate the software they need under Add/Remove Programs on their client computer. Windows does not ship with any categories by default.
	When upgrading deployed software, AD can either uninstall the old application first or upgrade over top of it.
	When publishing upgrades, they can be option or mandatory for users but are mandatory when assigned to computers.
	When applications are no longer supported, they can be removed from Software Installation without having to be removed from the systems of users who are using them. They can continue using the software until they remove it themselves, but no one else will be able to install the software through the Start menu, Add/Remove Programs, or by invocation.
	Applications that are no longer used can have their removal forced by an administrator. Software assigned to the user is automatically removed the next time that user logs on. When software is assigned to a computer, it is automatically removed at start up. Users cannot re-install the software.
	Selecting the "Uninstall this application when it falls out of the scope of management" option forces removal of software when a GPO no longer applies.

Configure deployment options:

	You can assign or publish software packages.
	Software that is assigned to a user has a shortcut appear on a user's Start > Programs menu, but is not installed until the first time they use it. Software assigned to a computer is installed the next time the user logs on regardless of whether or not they run it.
	When software is assigned to a user, the new program is advertised when a user logs on, but is not installed until the user starts the application from an icon or double-click a file-type associated with the icon. Software assigned to a computer is not advertised - the software is installed automatically. When software is assigned to a computer it can only be removed by a local administrator - users can repair software assigned to computers, but not remove it.
	The software settings of a Group Policy is not refreshed like the rest of the settings. The user may need to logoff/logon or the system may need to be restarted for the new settings to take place (depending on type of software installation).
	Published applications are not advertised. They are only installed through Add/Remove Programs in the Control Panel or through invocation. Published applications lack resiliency (do not self-repair or re-install if deleted by the user). Finally, applications can only be published to users, not computers.
	With invocation, when a user double-clicks on an unknown file type, the client computer queries Active Directory to see what is associated with the file extension. If an application is registered, AD checks to see if it has been published to the user. If it has, it checks for the auto-install permission. If all conditions are met, the application is invoked (installed).
	Non-MSI programs are published as .ZAP files. They cannot take advantage of MSI features such as elevated installation priveleges, rolling back an unsuccessful installation, installing on first use of software or feature, etc. (KB# Q231747) .ZAP files can only be published, not assigned.
	Non-MSI programs can be repackaged using a 3rd party tool on the W2K Server CD called WinINSTALL LE. It works like SYSDIFF as it lets you take a snapshot of a system, install your application, take another snapshot and create a difference file that becomes your MSI install package. If you wish to assign a non-MSI program to a user or computer, you must first repackage it as an MSI file. (KB# Q236573)
	When software requires a CD key during installation, it can be pushed down with the installer package by typing misexec /a <path to .msi file> PIDKEY="[CD-Key]" (KB# Q223393)
	Modifications are created using tools provided by the software manufacturer and produce .MST files which tell the Windows Installer what is being modified during the installation. .MST files must be assigned to .MSI packages at the time of deployment. (KB# Q236943)
	Patches are deployed as .MSP files. (KB# Q226936)

Configure and troubleshoot desktop settings:

Fax support:

	If a fax device (modem) is installed, the Fax applet appears in Control Panel. Does not appear when no fax device installed
	If the Advanced Options tab is not available in the Fax applet log off then log back on as Administrator
	Use the Fax applet to setup rules for how device receives faxes, number or retries when sending, where to store retrieved and sent faxes, user security permissions, etc.
	The Fax printer in your printer folder cannot be shared

Accessibility services: (KB# Q210894)

	Accessibility Wizard is used for deploying accessibility features to users who require them. Using the wizard, define the settings you want to deploy and, on the Save Settings to File page, save them to a file that has the .acw extension. Place the file on a network share and modify each user's login script so that it imports the settings. The command to import the file is this: %SystemRoot%\System32\Accwiz.exe filename. (KB# Q256956)
	Utility Manager enables users to check an Accessibility program's status, and start or stop an Accessibility program. Users with administrator-level access can designate to have the program start when Windows 2000 starts. The built-in programs accessible from the Utility Manager are Magnifier, Narrator, and On-Screen Keyboard.
	By default, automatic reset for accessibility options is disabled. When enabled, accessibilty options will be turned off if they have not be used for a pre-defined period of time. MS recommends enabling automatic reset on systems that are shared by more than one user.
	StickyKeys allows you to press multiple key combinations (CTRL-ALT-DEL) one key at a time
	FilterKeys tells the keyboard to ignore brief or repeated keystrokes
	SoundSentry displays visual warnings when your computer makes a sound (for aurally impaired)
	ShowSounds forces programs to display captions for the speech and sounds they make
	MouseKeys lets you control the mouse pointer with the numeric keypad
	Magnifier magnifies a portion of the desktop (for visually impaired) - available during GUI phases of OS installation (KB# Q231843)
	Narrator reads menu options aloud using speech synthesis (for visually impaired) - available during GUI phases of OS installation.

Implementing, Managing, and Troubleshooting Network Protocols and Services:

Miscellaneous:

	Is an industry-standard suite of protocols
	It is routable and works over most network topologies
	It is the protocol that forms the foundation of the Internet
	Installed by default in Windows 2000
	Can be used to connect dissimilar systems
	Uses Microsoft Windows Sockets interface (Winsock)
	IP addresses can be entered manually or provided automatically by a DHCP server
	DNS is used to resolve computer hostnames to IP addresses
	WINS is used to resolve a NetBIOS name to an IP address
	Subnet mask - A value that is used to distinguish the network ID portion of the IP address from the host ID.
	Default gateway - A TCP/IP address for the host (typically a router) which you would send packets for routing elsewhere on the network.

Automatic Private IP Addressing:

Windows 98 and Windows 2000 support this new feature. When "Obtain An IP Address Automatically" is enabled, but the client cannot obtain an IP address, Automatic Private IP addressing takes over:

	IP address is generated in the form of 169.254.x.y (where x.y is the computer's identifier) and a 16-bit subnet mask (255.255.0.0)
	The computer broadcasts this address to it's local subnet
	If no other computer responds to the address, the first system assigns this address to itself
	When using the Auto Private IP, it can only communicate with other computers on the same subnet that also use the 169.254.x.y range with a 16-bit mask.
	The 169.254.0.0 - 169.254.255.255 range has been set aside for this purpose by the Internet Assigned Numbers Authority

TCP/IP Server Utilities:

	Telnet server - Windows 2000 includes a telnet server service (net start tlntsvr) which is limited to a command line text interface and two concurrent users. Set security on your telnet server by running the admin tool, tlntadmn. (KB# Q225233)
	Web Server - stripped version of IIS5 Web server. Limited to 10 connections. Must be installed and service started before sharing your printers using Web printing or Internet printing. Can be managed using IIS snap-in or Personal Web Manager, a "dumbed-down" GUI for novice users.
	FTP Server - stripped version of Internet Information Server 5 (IIS5) FTP server. Limited to 10 connections but is adminstered just like the server version using IIS snap-in or the Personal Web Manager.
	FrontPage 2000 Server Extensions - extends the functionality of the Web server and included in W2K Pro for developing and testing Web sites before deploying them to a production server.
	SMTP Server - does not appear to have limitations on connections but this is most likely due to its integration with LDAP and Active Directory replication. Also works with the form handlers in FrontPage Server Extensions.

TCP/IP Client Utilities:

	Telnet client - Can be used to open a text based console on UNIX, Linux and Windows 2000 systems (run telnet servername)
	FTP client - Command line based - simple and powerful (run ftp servername)
	Internet Explorer 5 - Microsoft's powerful and thoroughly integrated Web browser (see IE5 Cramsession for details)
	Outlook Express 5 - SMTP, POP3, IMAP4, NNTP, HTTP, and LDAP complaint E-mail package.

Services for UNIX 2.0:

Miscellaneous:

	TCP/IP protocol is required for communicationg with UNIX hosts
	Windows 2000 uses CIFS (Common Internet File System) which is an enhanced version of the SMB (Server Message Block) protocol
	UNIX uses NFS (Network File System)
	FTP support has been added to Windows Explorer and to Internet Explorer 5.0 allowing users to browse FTP directories as if they were a local resource.
	Install SNMP for Network Management (HP, OpenView, Tivoli and SMS).
	Print Services for UNIX allows connectivity to UNIX controlled Printers (LPR)
	Simple TCP/IP Services provides Echo, Quote of Day, Discard, Daytime and Character Generator..

Client for NFS:

	Installs a full Network File System (NFS) client that integrates with Windows Explorer. Available for both W2K Professional and Server.
	Places a second, more powerful Telnet client on your system in the %windir%\system32\%sfudir% directory. This new client has been optimized for Windows NT Telnet server and can use NTLM authentication instead of clear text. (KB# Q250879)
	Users can browse and map drives to NFS volumes and access NFS resources through My Network Places. Microsoft recommends this over installing Samba (SMB file services for Windows clients) on your UNIX server.
	NFS shares can be accessed using standard NFS syntax (servername:/pathname) or standard UNC syntax (\\servername\pathname)
	If users' UNIX username/password differ from Windows username/password, click "Connect Using A Different User Name" option and provide new credentials.
	The following popular UNIX utilities are installed along with the Client for NFS (not a complete list):

The nfsadmin command-line utility is used for configuration and administration of the Client for NFS. It's options are:

Server for NFS:

	Allows NFS clients (think UNIX/Linux here) to access files on a Windows 2000 Professional or Server computer.
	Integrates with Server for PCNFS or Server for NIS to provide user authentication
	Managed using the UNIX Admin Snap-in (sfumgmt.msc)

Gateway for NFS:

	Allows non-NFS Windows clients to access NFS resources by connecting thru an NFS-enabled Windows Server to NFS resources.
	Acts as a gateway/translator between the NFS protocol used by UNIX/Linux and the CIFS protocol used by Windows 2000.
	Not available on W2K Professional - Server only.

Server for PCNFS:

	Can be installed on either W2K Professional or Server
	Provides authentication services for NFS clients (UNIX) needing to access NFS files. Works with the mapping server.

Server for NIS:

	Must be installed on a Windows 2000 Server that is configured as a Domain Controller.
	Allows server to act as the NIS master for a particular UNIX domain.
	Can authenticate requests for NFS shares.

Troubleshooting: (KB# Q102908)

	Ipconfig and Ipconfig /all - displays current TCP/IP configuration
	Nbtstat - displays statistics for connections using NetBIOS over TCP/IP
	Netstat - displays statistics and connections for TCP/IP protocol
	Ping - tests connections and verifies configurations
	Tracert - check a route to a remote system
	Common TCP/IP problems are caused by incorrect subnet masks and gateways
	If an IP address works but a hostname won't check DNS settings

NWLink (IPX/SPX) and NetWare Interoperability: (KB# Q220872)

	NWLink (MS's version of the IPX/SPX protocol) is the protocol used by NT to allow Netware systems to access its resources. (KB# Q203051)
	NWLink is all that you need to run in order to allow an NT system to run client/server applications from a NetWare server.
	To allow file and print sharing between NT and a NetWare server, CSNW (Client Services for NetWare) must be installed on the NT system. In a Netware 5 environment, the Microsoft client does not support connection to a Netware Server over TCP/IP. You will have to use IPX/SPX or install the Novell NetWare client. (KB# Q235225)
	W2K Setup upgrades all Intel x86 based computers running version 4.7 or earlier of a Novell client to version 4.51. (KB# Q218158)
	Gateway Services for NetWare can be implemented on your NT Server to provide a MS client system to access your NetWare server by using the NT Server as a gateway. (KB# Q121394 & Q220872)
	Frame types for the NWLink protocol must match the computer that the NT system is trying to connect with. Unmatching frame types will cause connectivity problems between the two systems.
	When NWLink is set to autodetect the frame type, it will only detect one type and will go in this order: 802.2, 802.3, ETHERNET_II and 802.5 (Token Ring).
	Netware 3 servers uses Bindery Emulation (Preferred Server in CSNW). Netware 4.x and higher servers use NDS (Default Tree and Context.)
	There are two ways to change a password on a netware server - SETPASS.EXE and the Change Password option (from the CTRL-ALT-DEL dialog box). The Change Password option is only available to Netware 4.x  and higher servers using NDS.

Other protocols:

	DLC is a special-purpose, non-routable protocol used by Windows 2000 to talk with IBM mainframes, AS400s and Hewlett Packard printers.
	Appletalk must be installed to allow Windows 2000 Professional to communicate with Apple printers. Do not confuse this with File and Print Services for Macintosh which allow Apple Clients to use resources on a Microsoft Network (only available on Server).
	NetBEUI is used soley by Microsoft operating systems and is non-routable (it is broadcast-based)

Remote Access Services (RAS):

Authentication protocols:

	EAP - Extensible Authentication Protocol. A set of APIs in Windows for developing new security protocols as needed to accomodate new technologies. MD5-CHAP and EAP-TLS are two examples of EAP
	EAP-TLS - Transport Level Security. Primarily used for digital certificates and smart cards
	MD5-CHAP - Message Digest 5 Challenge Handshake Authentication Protocol. Encrypts usernames and passwords with an MD5 algorithm
	RADIUS - Remote Authentication Dial-in User Service. Specification for vendor-independant remote user authentication. Windows 2000 Professional can act as a RADIUS client only.
	MS-CHAP (v1 and 2) - Microsoft Challenge Handshake Authentication Protocol. Encrypts entire session, not just username and password. v2 is supported in Windows 2000 and NT4 and Win 95/98 (with DUN 1.3 upgrade) for VPN connections. MS-CHAP cannot be used with non-Microsoft clients
	SPAP - Shiva Password Authentication Protocol. Used by Shiva LAN Rover clients. Encrypts password, but not data
	CHAP - Challenge Handshake Authentication Protocol - encrypts user names and passwords, but not session data. Works with non-Microsoft clients
	PAP - Password Authentication Protocol. Sends username and password in clear text

Virtual Private Networks (VPNs):

	PPTP - Point to Point Tunneling Protocol. Creates an encrypted tunnel through an untrusted network.
	L2TP - Layer Two Tunneling Protocol. Works like PPTP as it creates a tunnel, but it does not provide data encryption. Security is provided by using an encryption technology like IPSec

Multilink Support: (KB# Q235610)

	Multilinking allows you to combine two or more modems or ISDN adapters into one logical link with increased bandwidth. (KB# Q233171)
	BAP (Bandwidth Allocation Protocol) and BACP (Bandwidth Allocation Control Protocol) enhance multilinking by dynamically adding or dropping links on demand. Settings are configured through RAS policies. (KB# Q244071)
	Enabled from the PPP tab of a RAS server's Properties dialog box. (KB# Q233151)

Setting Callback Security:

	Using callback allows you to have the bill charged to your phone number instead of the number of the user calling in. Also used to increase security
	For roving users like a sales force, choose "Allow Caller to Set The Callback Number" (less secure)

Dial-up networking:

	Microsoft technical documentation generally refers to dial-up networking when describing outbound connections. Inbound connections are usually associated with Remote Access Services (RAS).
	All new connections are added using the "Make New Connection" wizard.
	To create a VPN connection, choose Dial-Up To A Private Network Through The Internet, specify whether you need to establish a connection with an ISP first, enter the host name or IP address of the computer/network you are connecting to, and select whether connection is for yourself or all users.
	Dial-up networking entries can be created for modem connections, LAN connections, direct cable connections and Infrared connections.
	PPP is generally prefered because it supports multiple protocols, encryption, and dynamic assignment of IP addresses (KB# Q124036). SLIP is an older protocol that only supports TCP/IP and is used for dialing into legacy UNIX systems.
	All network connections, inbound and outbound, are represented by separate icons under Dial-up networking and properties, protocols, addresses and services can be individually configured for each.

Using shared resources on a Microsoft Network:

Full Control	Is assigned to the Everyone group by default. Allows user to take ownership of files and folders. Users can change file access rights. Grants user all permissions assigned by the Change and Read levels.
Change	User can add and create files. Grants ability to modify files. User can change the attributes of the file. User can delete files. Grants user all permissions assigned by the Read level.
Read	User can display and open files. User can display the attributes of the file. User can execute program files.
No Access	User cannot display, access, or modify files.

Active Directory (AD) srevices provide a single point of network management, allowing you to add, remove, and relocate resources easily. It offers significant enhancements over the limitations of the older Windows NT domain based security model. It's features are:

	Simplified Administration - AD provides a single point of logon for *all* network resources - an administrator can logon to one computer and administer objects on any computer in the network.
	Scalability - NT 4 domains had a practical limitation of about 40,000 objects. AD scales to millions of objects, if needed.
	Open standards support - uses DNS as it's domain naming and location service so Windows 2000 domain names are also DNS domain names. Support for LDAP v2 and v3 makes AD interoperable with other directory services that support the same, such as Novell's NDS. HTTP support means that AD can be searched using a Web browser. Kerberos 5 support provides interoperability with other products that use the same authentication mechanism.

Active Directory Structure:

	Object - distinct named set of attributes that represents a network resource such as a computer or a user account.
	Classes - logical groupings of objects such as user accounts, computers, domains or organizational units.
	Organizational Unit (OU) - container used to organize objects inside a domain into logical administrative groups such as computers, printers, user accounts, file shares, applications and even other OUs.
	Domain - all network objects exist within a domain with each domain storing information only about the objects it contains. A domain is a security boundry - access to objects is controlled by Access Control Lists (ACLs). ACLs contain the permissions associated with objects that control which users or types of users can access them. In Windows 2000, all security policies and settings (like Administrative rights) do not cross from one domain to another. The domain admin only has right to set policies within his/her domain.
	Tree - a grouping or hierarchical arrangement of one or more Windows 2000 domains that share a contiguous names space (e.g. cramsession.brainbuzz.com, sales.brainbuzz.com, and jobs.brainbuzz.com). All domains inside a single tree share a common schema (formal definition of all object types that can be stored in an AD deployment) and share a common Global Catalog.
	Forest - a grouping or hierarchical arrangement of one or more domain trees that form a disjointed namespace (e.g. cramsession.com and brainbuzz.com). All trees in the forest share a common schema and Global Catalog, but have different naming structures. Domains in a forest operate independently of each other, but the forest enables communication across the domains.
	Sites - combination of one or more IP subnets connected by high-speed links. Not part of the AD namespace, and contains only computer objects and connection objects used to configure replication between sites.

Site Replication:

	Active Directory information is replicated between Domain Controllers (DCs) and ensures that changes to a domain controller are reflected in all DCs within a domain. A DC is a computer running Windows 2000 server which contains a replica of the domain directory (member servers do not).
	DCs store a copy of all AD information for their domain, manage changes to it and copy those changes to other DCs in the same domain. DCs in a domain automatically copy all objects in the domain to each other. When you change information in AD, you are making the change on one of the DCs.
	Administrators can specify how often replication occurs, at what times, and how much data can be sent.
	DCs immediately replicate important changes to AD like a user account being disabled.
	AD uses multimaster replication meaning that no one DC is the master domain controller - all DCs within a domain are peers (however there are still some roles called Operations Master roles that can only be held by one DC at a time).
	Having more than one DC in a domain provides fault-tolerance. If a DC goes down, another is able to continue authenticating logins and providing required services using it's copy of AD.
	Replication is automatically generates a ring topology for replication in the same domain and site. The ring ensures that if one DC goes down, it still has an available path to replicate it's information to other DCs.

Active Directory Concepts:

Active Directory Naming Conventions:

	Distinguished Name (DN) - every object in AD has one. Uniquely identifies object and contains sufficient info for an AD client to retrieve it from the Directory. Includes the name of the domain that holds the object and also the complete path through the container hierarchy to it. DNs must be unique - AD will not allow duplicates.
	Relative Distingushed Name (RDN) - if the DN is unknown, you can still query an object by it's attributes. The RDN is a part of the name that is an attribute of the object itself (e.g. a user's first name and location).
	Globally Unique Identifier (GUID) - unique 128-bit number assigned to objects when they are created. The GUID never changes so even if the object is renamed or moved, the GUID can be used to locate it.
	User Principal Name (UPN) - "friendly name" given to a user account (e.g. johndoe@brainbuzz.com).

Local user accounts: (KB# Q217050)

	Resides only on the computer where the account was created in it's local security database. If computer is part of a peer-to-peer workgroup, accounts for that user will have to be created on each additional machine that they wish to log onto locally. Local accounts cannot access Windows 2000 domain resources and should not be created on computers that are part of a domain.
	Domain user accounts reside in AD on domain controllers and can access all resources on a network that they have been accorded priveleges for.
	Built in user accounts are Administrator (used for managing the local system) and Guest (for occasional users - disabled by default)
	Usernames cannot be longer than 20 characters and cannot contain the following illegal characters: " / \ [ ] : ; | = , + * ? < >
	User logon names are not case sensitive. You can use alphanumeric combinations to increase security, if desired.
	Passwords can be up to 128 characters (we're not kidding!!) but Microsoft recommends limiting them to about eight characters.
	The same characters that are considered illegal in usernames are also verbotten for use in passwords
	User accounts are added and configured through the Computer Management snap-in.
	MS recommends that users be encouraged to store their data in their My Documents folder which is automatically created within their profile folder and is the default location that Microsoft applications use for storing data. This folder should not be used with roaming profiles unless it has been redirected to a network file share.
	Creating and duplicating accounts requires only two pieces of information: username and password. Disabling an account is typically used when someone else will take the user's place or when the user might return.
	Delete an account only when absolutely necessary for space or organization purposes.
	When copying a user account, the new user will stay in the same groups that the old user was a member of. The user will keep all group rights that were granted through groups, but lose all individual rights that were granted specifically for that user.

Local user authentication:

System Policy Editor (poledit.exe) - Windows NT 4, Windows 95 and Windows 98 all use the System Policy Editor (poledit.exe) to specify user and computer configuration that is stored in the registry.

	Not secure because settings can be changed by a user with the Registry Editor (regedit.exe). Settings are imported/exported using .ADM templates.
	Are considered "undesirabley persistant" as they are not removed when the policy ends.
	Windows 2000 comes with system.adm (system settings), inetres.adm (Internet Explorer settins) and conf.adm (NetMeeting settings) although the latter is not loaded by default.

Group Policy snap-in (gpedit.msc) - Exclusive to Windows 2000 and supercedes the System Policy Editor. Uses Incremental Security Templates.

	Should only be applied to Windows 2000 systems that have been clean installed onto an NTFS partition. NTFS computers that have been upgraded from NT4 or earlier, only the Basic security templates can be applied.
	Settings can be stored locally or in AD. Are secure and cannot be changed by users - only Administrators.
	More flexible than System Policies as they can be filtered using Active Directory.
	Settings are imported/exported using .INF files. The Group Policy snap-in can be focused on a local or remote system.

Incremental Security Templates for Windows 2000:

Local Group Policy:

	There are two types of Group Policy objects: local Group Policy objects and non-local Group Policy Objects. Each Windows 2000 system can have only one local Group Policy object.
	Order of application is Local, Site, Domain and Organizational Unit. Local Policies have the least precedence whereas OU Policies have the highest.

Non-local Group Policy (stored in Active Directory):

	Can be linked to a site with AD Sites and Services and applies to all domains at the site
	When applied to a domain it affects all users and computers in the domain and (by inheritance) all users and computers in Organizational Units.

Config.pol, NTConfig.pol and Registry.pol:

	Windows 2000 uses the registry.pol format. Two files are created, one for Computer Configuration (stored in the \Machine subdirectory) and one for User Configuration (stored in the \User subdirectory).
	Registry.pol files can be used with Windows 95/98, Windows NT 4.0 and Windows 2000 as it is a text file embedded with binary strings. NTConfig.pol is a binary file whereas Config.pol is a text file.
	.POL files can be viewed using the regview.exe tool from the W2K Resource Kit. Viewing them does not apply them to the registry.

About EFS:

	Only works on Windows 2000 NTFS partions (NTFS v5).
	Encryption is transparent to the user.
	Uses public-key encryption. Keys that are used to encrypt the file are encrypted by using a public key from the user's certificate.The list of encrypted file-encryption keys is kept with the encrypted file and is unique to it. When decrypting the file encryption keys, the file owner provides a private key which only he has. (KB# Q241201 & Q230490)
	If the owner has lost his private key, an appointed recovery system agent can open the file using his/her key instead. (KB# Q242296)
	There can be more than one recovery agent, but at least one public recovery key must be present on the system when the file is encrypted.
	EFS resides in the Windows OS kernel and uses the non-paged memory pool to store file encryption keys - this means no one will be able to extract them from your paging file.
	Encrypted files can be backed up using the Backup Utility, but will retain their encrypted state as access permissions are preserved. (KB# Q227825 & Q223178)
	Microsoft recommends creating an NTFS folder and encrypting it. In the Properties dialog box for the folder click the General tab then the Advanced button and select the "Encrypt Contents To Secure Data" check box. The folder isn't encrypted, but files placed in it will be automatically encrypted. Uncheck the box if you want to decrypt the file.
	Default encryption is 56-bit. North Americans can upgrade to 128-bit encryption.
	Compressed files can't be encrypted and vice versa. (KB# Q223093)
	You can't share encrypted files
	Use the Cipher command to work with encrypted files from the command line. (KB# Q229530) & Q229546)
	Encrypted files are decrypted if you copy or move them to a FAT volume (remember that floppies are always formatted as FAT).
	Cut and paste to move files into an encrypted folder - if you drag and drop files, the files are not automatically encrypted in the new folder.
	The efsinfo.exe utility in the W2K Resource Kit allows an administrator to determine information about encrypted files (KB# Q243026)

Using the CIPHER command:
