The Netlogon subkey stores information for the Net Logon service.
The Net Logon service verifies logon requests, and it registers, authenticates, and locates domain controllers. Also, to maintain backward compatibility, Net Logon manages replication of the user account database to back up domain controllers running Windows NT 4.0 and earlier.
For Windows 2000, Net Logon manages replication only when replication involves servers running Windows NT 4.0 and earlier. Net Logon for Windows 2000 does not manage replication between two servers running Windows 2000.

What are the services start after active directory installation in server?
netlogon dns rpc active directory services(it is in form of service in win2008 only) these are the major ones
Are the SRV records of a child domain updated automatically during Active Directory installation?
After running DCPROMO, A text file containing the appropriate DNS resource records for the domain controller is created. The file called Netlogon.dns is created in the %systemroot%\System32\config folder and contains all the records needed to register the resource records of the domain controller. Netlogon.dns is used by the Windows 2000 NetLogon service and to support Active Directory for non-Windows 2000 DNS servers. If you are using a DNS server that supports the SRV resource record but does not support dynamic updates (such as a UNIX-based DNS server or a Windows NT Server 4.0 DNS server), you can import the records in Netlogon.dns into the appropriate primary zone file to manually configure the primary zone on that server to support Active Directory. so if you are using w2k with dynamic update it will automatically create the SRV
Unable to logon because the net logon service is not running on this machine?
Hi, In this case you can do either one of the following:- *Boot into the Safe Mode : - You can boot in to the safe mode if you can by pressing the f8 button on startup and choosing boot in safe mode from the options menu, Login with the local admin and try itReboot into the safe mode and try start the service. * System Restore :You can boot in to the safe mode if you can, by pressing the f8 button on startup and choosing boot in safe mode from the options menu, Login with the local admin and try it. It restores the system to previously good working stage, So chances are you might able to login in to the system. * Through Recovery Console : Insert the windows xp CD in to the CD-ROM and start the system. Login into the recovery console. To login in to the recovery console Press R when welcome to the Windows xp professional screen appears. Select the partition number normally in most of the cases its 1, provide the administrator id and password, Type net start netlogon at the prompt, exit and reboot the system. Regards, R
How do you install updates to all client machines from server using GPO?
Download the "Windows-en-US-KB943729.exe" update and place it into the \domain-controller-name\netlogon folder.Create a new group policy object linked to an OU above the client computers. If they're in the default "Computers" container at the root of the directory, create this new GPO at the root of the directory. Name the GPO something like "Install KB943729 Update to Windows XP Clients" (something you'll remember in 6 months).In that new GPO, go to "Computer Configuration", "Windows Settings", and "Scripts". Head into the "Startup Scripts" dialog.Click the "Show Files..." button in the Startup Scripts" dialog. Create a new text file there, and rename it to something like "Install_KB943729.cmd" (be sure it loses the ".TXT" extension). Right-click and "Edit" that file in Notepad.Paste the script below these steps into that file and save it. Be sure to modify the "SET DC_NAME=" line of the script to indicate your domain controller computer's name after the "=" (no "" before name, etc).Return to the "Startup Scripts" dialog (closing the folder opened by "Show Files...") and click "Add...". Click "Browse..." and choose the "Install_KB943729.cmd" you created. (Verify again that the ".txt" extension has been changed, too.)Close the "Startup Scripts" dialog. Go into "Administrative Templates" under "Computer Configuration". Dig down to "System" and "Scripts". Locate the policy setting in the right pane "Run startup scripts visible" and set the setting to "Enabled". This will let you see the script run in a Window during boot on the clients. Once you know the script is running okay you can turn this setting off.Reboot a client and see the script run during boot. Assuming all your DNS settings are good, etc, the client will have the GPO you created applied and run the script.When all the clients are updated either delete the GPO and the .EXE in the "Netlogon" folder, unlink the GPO and keep it around should you need it in the future. (Running a startup script on every computer needlessly on every boot will add some minor delay to boot. There are ways with group membership that you could make this more elegant and only execute once, but I'm going for quick-and-dirty here.)The script to paste: @echo off SET DC_NAME=domain-controller-computer-name-here rem Check to see this is Windows XP ver | find "Windows XP" >NUL if errorlevel 1 goto end rem Check to see if the update is already installed reg QUERY "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\Windows XP\SP20\KB943729" >NUL 2>NUL if errorlevel 1 goto install_update goto end :install_update \\%DC_NAME%\netlogon\Windows-en-US-KB943729.exe /passive /norestart :endIt would be better if you installed Windows Server Update Services and pushed out the update that way, since it would also give you centralized deployment of Windows / Microsoft application software updates in the future, but that's a bigger can of worms. Have a look at it, though. You want to be using WSUS.I'm happy to see you're looking into using Group Policy. Many Windows admins have no idea about it. I've been in some very large companies (one a Fortune 1000 company) that didn't use Group Policy at all (in 2008, no less). If you're not already familiar with how policy application order works, how to dofiltering by security groups or WMI filters, you should do some reading-up and trial exercises, because you'll like those features and find them handy. (For bonus points, learn about Loopback Group Policy Processing for added fun and functionality.)
What does the sysvol folder stores in an active directory?
The sysVOL folder stores the server's copy of the domain's public files. The contents such as group policy, users etc of the sysvol folder are replicated to all domain controllers in the domain. The sysvol folder must be located on an NTFS volume The article describes how to use the Burflags registry entry to rebuild each domain controller's copy of the system volume (SYSVOL) tree on all domain controllers in a common Active Directory directory service domain. The term SYSVOL refers to a set of files and folders that reside on the local hard disk of each domain controller in a domain and that are replicated by the File Replication service (FRS). Network clients access the contents of the SYSVOL tree by using the following shared folders:
How do you backup Active Directory and which main file you take in backing of Active Directory?
We can take backup with NTBackup utility.Active Directory is backed up as part of system state, a collection of system components that depend on each other. You must backup and restore system state components together. Components that comprise the system state on a domain controller include:System Start-up Files (boot files). These are the files required for Windows 2000 Server to start.System registry.Class registration database of Component Services. The Component Object Model (COM) is a binary standard for writing component software in a distributed systems environment.SYSVOL. The system volume provides a default Active Directory location for files that must be shared for common access throughout a domain.The SYSVOL folder on a domain controller contains: NETLOGON shared folders. These usually host user logon scripts and Group Policy objects (GPOs) for non-Windows 2000based network clients.User logon scripts for Windows 2000 Professional based clients and clients that are running Windows 95, Windows 98, or Windows NT 4.0.Windows 2000 GPOs.File system junctions.File Replication service (FRS) staging directories and files that are required to be available and synchronized between domain controllers.Active Directory. Active Directory includes: Ntds.dit: The Active Directory database.Edb.chk: The checkpoint file.Edb*.log: The transaction logs, each 10 megabytes (MB) in size.Res1.log and Res2.log: Reserved transaction logs.
What is the SYSVOL folder?
All active directory data base security related information store in SYSVOL folder and its only created on NTFS partition. B: The Sysvol folder on a Windows domain controller is used to replicate file-based data among domain controllers. Because junctions are used within the Sysvol folder structure, Windows NT file system (NTFS) version 5.0 is required on domain controllers throughout a Windows distributed file system (DFS) forest. This is a quote from Microsoft themselves, basically the domain controller info stored in files like your group policy stuff is replicated through this folder structure
