Performing an Authoritative System State Restore for a Windows 2000 or 2003 Domain
Controller
Important: Incorrectly restoring a computer's
Windows 2000/2003 System State can make the computer unusable. We generally recommend
that you restore the System State only when recovering the entire computer as
part of a disaster recovery. See Restoring an Entire Computer
and contact Customer Service.
Usually it is not necessary to perform an authoritative System State restore.
However, it may be necessary in some instances, for example, if your replicated
Active Directory objects were mistakenly deleted or modified, or if your backup
domain database is corrupted. The authoritative restore allows you to restore
the System State data (such as Active Directory Service) to your Primary Domain Controller and have it replicated to
your other domain controllers. For assistance in determining whether you need to
perform an authoritative restore, see
Non-Authoritative Versus
Authoritative Restore and consult your Windows 2000/2003 documentation. You can
also contact Customer Service for assistance.
If it is determined that you must perform an authoritative System State
restore as part of a disaster recovery for your Primary Domain Controller,
during the disaster recovery you will first restore the System State in
non-authoritative mode. Following the completion of the steps in the disaster recovery
procedure up to the point at which they direct you to this procedure, you will
then perform the authoritative restore steps in this topic. After completing the
steps in this topic, you will return to the disaster recovery procedure to
complete the recovery process.
If your backup domain database is corrupted, you may need to perform
these steps several times, using the Time-Slice restore to bring back historical
versions until you find a version from before the corruption.
Important: The Active Directory and Certificate Services cannot be running on the domain
controller during the restore process.
Note: The ability to restore the
System State on media may not be available to your Agent
at this time. In this case, you will not see a Delivery tab on the
Computer Restore form. Instead, you can restore the System State over the
Internet. If you have questions, contact Customer Service.
