- The COM+ class
registration database

Windows 2000 Backup can back
up and restore Active Directory on Windows 2000 domain controllers. You

booted into Directory Services Restore mode (by pressing the F8 key when
the server is booting).

How to Back Up the System
State on a Domain Controller
- Click Start, point to
Programs, point to Accessories, point to System Tools, and then
click Backup.
- Click the Backup tab.
- Click to select the
System State check box. (All of the components to be backed up are
listed in the right pane. You cannot individually select each item.)
NOTE: During the system state backup, you must select to back up the
Winnt\Sysvol folder. You must also select this option during the
restore operation to have a working sysvol after the recovery.
The following information
applies only to domain controllers. You can restore member servers the
same way, but in normal mode.
If any of the following conditions are not met, the system state is not
restored. Backup attempts to restore the system state, but does not
succeed.
- The drive letter on
which the %SystemRoot% folder is located must be the same as when it
was backed up.
- The %SystemRoot% folder
must be the same folder as when it was backed up.
- If sysvol or other
Active Directory databases were located on another volume, they must
exist and have the same drive letters also. The size of the volume
does not matter.
How to Restore the System
State on a Domain Controller
TOP
- To restore the system
state on a domain controller, first start the computer in Directory
Services Restore Mode. To do so, restart the computer and press the
F8 key when you see the Boot menu.
- Choose Directory
Services Restore Mode.
- Choose the Windows 2000
installation you are going to recover, and then press ENTER.
- At the logon prompt,
supply the Directory Services Restore mode credentials you supplied
during the Dcpromo.exe process.
- Click OK to acknowledge
that you are using Safe mode.
- Click Start, point to
Programs, point to Accessories, point to System Tools, and then
click Backup.
- Click the Restore tab.
- Click the appropriate
backup media and the system state to restore.
NOTE: During the restore operation, the Winnt\Sysvol folder must
also be selected to be restored to have a working sysvol after the
recovery process. Be sure that the advanced option to restore
"junction points and data" is also selected prior to the
restore. This ensures that sysvol junction points are re-created.
- In the Restore Files to
box, click Original Location.
NOTE: When you choose to restore a file to an alternative location
or to a single file, not all system state data is restored. These
options are used mostly for boot files or registry keys.
- Click Start Restore.
- After the restore
process is finished, restart the computer.
