Challenge

After restoring a Domain Controller, it appears to get stuck in safe mode.

Cause

When restoring a Domain Controller from a backup, the DC will enter Directory Services Restore Mode (DSRM) during the first boot. It should reboot on its own into a non-authoritative state after a short time.

Solution

If the DC does not reboot on its own, or you would like to force it out of DSRM, modify the bcd using the following commands.

To do this, you may have to log in using the Directory Services Restore Mode account, typically .\administrator.

Open a command prompt and run the following:

bcdedit /deletevalue safeboot
shutdown -t 01 -r
Afterward, it should boot into normal mode.
