Perform a BMR and Access the Directory Services Repair Mode

There are two parts to the authoritative restore process: a non-authoritative restore is performed first by running a BMR, and then an authoritative restore of the deleted Active Directory objects is performed. As a result, you must make sure that the domain controller that is recovered by the BMR does not automatically reboot before you can access the Directory Services Repair Mode to perform the second part of the process (authoritative restore).

Follow these steps:

1. Perform a BMR for the domain controller that you want to recover, and when the Bare Metal Recovery Summary of Restore Settings dialog is displayed, uncheck Automatically reboot your system after recovery option.

   For more information, see How to Perform a BMR Using a Backup or How to Perform a BMR Using a Virtual Standby VM.

   Important: Do not reboot the domain controller normally after BMR, or else you will lose the opportunity to perform the authoritative restore.The authoritative restore must be performed after you complete the BMR process, but before you fully reboot the recovered domain controller.

2. When the BMR process is completed, initiate a reboot and during the reboot process press F8 to display the Advanced Boot Options screen.
3. From the Advanced Boot Options screen, select the Directory Services Repair Mode and wait for the system to boot up into Directory Services Repair Mode.
