1. | Log on to the Windows Server 2008 R2 domain controller system with an account with administrator privileges.
|
2. | Click Start, click All Programs, click Administrative Tools, and select System Configuration.
|
3. | Select
the Boot tab. In the Boot Options section, check the Safe Boot check
box, select the Active Directory Repair option button, as shown in Figure 2, and then click OK.
|
4. | The
System Configuration utility will ask for a reboot, and if there are no
additional tasks to perform, click the Restart button to boot the
system into DSRM.
|
5. | When
the system completes a reboot, log on as administrator with the DSRM
password. Make sure to specify the local server as the logon domain—for
example, server10\administrator instead of companyabc\administrator.
|
6. | Click Start, click All Programs, click Administrative Tools, and select Windows Server Backup.
|
7. | In the Actions pane, select Recover to start the Recovery Wizard.
|
8. | On the Getting Started page, select This Server (Servername), where Servername is the name of the server to which Windows Server Backup is connected, and click Next to continue.
|
9. | On
the Select Backup Date page, select the correct date and time of the
backup you will use to restore the data, and click Next to continue.
Days with a successful backup are formatted in boldface.
|
10. | On the Select Recovery Type page, select the System State option button, and click Next to continue.
|
11. | On
the Select Location for System State Recovery page, select the Original
Location option button. Do not check the Perform an Authoritative
Restore of Active Directory Files check box unless the sysvol folder
and content will be marked as the definitive/authoritative copy and
replicated to all other domain controllers. For our example, we will
recover the System State but not mark the SYSVOL as an authoritative
restore, as shown in Figure 3. Click Next to continue.
|
12. | A
dialog box opens that states that this recovery option will cause the
server to resynchronize after recovery; click OK to continue.
|
13. | On
the Confirmation page, verify that the System State is listed and that
the check box to automatically reboot the server is not checked. Click
Recover to start the System State recovery of the domain controller.
|
14. | A
dialog box opens, detailing that once the recovery is started, it
cannot be paused, and a restart will be required to complete the
recovery. Click Yes to start the recovery. System State recovery can
take a long time to complete; please be patient.
|
15. | Once
the System State restore completes, even if the check box to
automatically reboot is not checked, Windows Server Backup will present
a dialog box with a Restart button and no other option. Restart the
server now.
|
16. | Once the server reboots, it will reboot into DSRM again. Log on with the DSRM local username and password.
|
17. | Once logged in, a wbadmin command prompt opens, stating that the restore completed successfully. Close the command prompt.
|
18. | Click Start, click All Programs, click Administrative Tools, and select System Configuration.
|
19. | Select the Boot tab. In the Boot Options section, uncheck the Safe Boot check box and click OK.
|
20. | If
an authoritative restore of Active Directory objects is not required,
click the Restart button in the dialog box and allow the server to
reboot normally.
|
21. | If
an authoritative restore is required, click the Exit Without Restart
button in the dialog box and perform the steps outlined in the “Active Directory Authoritative Restore” section. |
