We have 2 domain controllers, the primary DC is down and It cannot login to windows due to an error:
“Security Accounts Manager initialization failed because of the following error: Directory Service cannot start. Error Status: 0x0c00002e1. Please click OK to shutdown this system and reboot into Directory Services Restore Mode, check the event log for more detailed information.”
I want to restore the Primary DC and these are my options:
Restore the Primary DC from an OLD system state backup (from May) then synchronize/update from the Secondary Dc to the Primary DC, Is this possible?
Restore the Active directory from an Acronis Backup File (2-3 weeks ago). Note: The Acronis software is a trial version and it’s already expired. I still have the backup file and the recovery disk. My intention is to copy/paste the Active Directory Database from the backup to the damaged Primary DC. Will this work?
Reinstall Windows and make it as a DC. Note: This server is x86, I want to make it x64. I don’t know if this will work because the Secondary DC still have the Primary DC’s objects in the Active Directory. Do I have to remove the Primary DC from the Secondary DC’ AD database?
What’s would be the best option in this situation?
