Delay Windows (member) Server start-up until Domain Controller is available
Solution 1:
The easiest solution would be to activate WOL and run a startup script on the domain controller that sends the WOL magic packet to the other servers.
You would have to configure the BIOS/UEFI of the servers to
- power up all domain controllers after a power failure when the power is restored, and
- to keep all other servers powered off after a power failure, and
- activate WOL.
