Domain Controller starts up in Safe Mode

Challenge
After doing a full Virtual Machine restore, Instant Recovery, or testing of a Replica, you will find that the Virtual Machine boots up in what appears to be safe mode.
When the Domain Controller boots for the first time it is actually in Active Directory services restore mode.

Cause
This is normal for this to happen as we're booting from a backup file, however it should reboot automatically.

Solution
Login with the Directory services restore mode account (typically .\administrator) and open a command prompt and run the following:
C:/>bcdedit /set safeboot dsrepair
C:/>bcdedit /deletevalue safeboot
C:/>shutdown -t 01 -r
Afterwards it should reboot in normal mode.
