"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.
To prepare the domain, run Adprep.exe from the installation DVD on your existing domain controller that hosts the infrastructure master role. In Windows Server 2008, Adprep.exe is located in the /Sources/adprep folder of the operating system installation DVD. In Windows Server 2008 R2, Adprep.exe is located in the /Support/adprep folder.
Active Directory is backed up as part of system state, a collection of system components that depend on each other. You must back up 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 Professionalbased 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.
Note: If you use Active Directory-integrated DNS, then the zone data is backed up as part of the Active Directory database. If you do not use Active Directory-integrated DNS, you must explicitly back up the zone files. However, if you back up the system disk along with the system state, zone data is backed up as part of the system disk.If you installed Windows Clustering or Certificate Services on your domain controller, they are also backed up as part of system state. Details of these components are not discussed in this guide.
