Thankfully all my DCs are not really corrupt, but I am developing a plan incase that happens or if all DCs are lost. &nbsp;I'm looking for help filling in the holes that I have missed and to correct any information that is not valid. &nbsp;My plan would be to boot one of the DCs into Directory Restore Mode and perform an authoritative restore of the system state on that DC. &nbsp;Once the authoritative restore is complete, would the other corrupt DCs receive the restored database via replication?<br />
<br />
To perform the authoritave restore, we would restore the System State using Backup Exec, reboot the DC back into Directory Services Restore Mode, Start ntdsutil, type ntdsutil: authoritative restore, mark the entire database as authoritative by typing authoritative restore: restore database<br />
<br />
Anything that I'm missing? &nbsp;Thanks for any help!

All my DCs are corrupt...atleast for this scenario

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Storage Software

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.
