How to Restore the System State on a Domain Controller
loadTOCNode(2, 'summary');
1.
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.
2.
Choose
Directory Services Restore Mode.
3.
Choose the Windows 2000 installation you are going to recover, and then press ENTER.
4.
At the logon prompt, supply the Directory Services Restore mode credentials you supplied during the Dcpromo.exe process.
5.
Click
OK to acknowledge that you are using Safe mode.
6.
Click
Start, point to
Programs, point to
Accessories, point to
System Tools, and then click
Backup.
7.
Click the
Restore tab.
8.
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.
9.
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.
10.
Click
Start Restore.
11.
After the restore process is finished, restart the computer.
NOTICE: If you do not want to proceed with PC Restore, click Reboot in the following step.
The restore process takes approximately 6–10 minutes to complete.
NOTE: Do not manually shut down the computer. Click Finish and let the computer completely reboot.
The computer restarts. Because the computer is
restored to its original operating state, the screens that appear, such
as the End User License Agreement, are the same ones that appeared the
first time the computer was turned on.
