Active Directory and more….

AD Recovery

Posted by chrisbeams on May 22, 2009

So my progress to date has been good.  I have used the Quest Recovery Manager for AD in my home lab to recover a child domain and two domain controllers.  To be honest it was a very simple process and after a few nervous minutes while the existing DCs sorted themselves out everything was ok.  I have some screen shots and a short guide that I will post early next week. It was intersting to see the invocation guid changing as the DC worked out it had been restored.

Active Directory has been restored from backup media, or has been configured to host an application partition. The invocationID attribute for this domain controller has been changed. The highest update sequence number at the time the backup was created is as follows.
InvocationID attribute (old value):
216d1df4-db3d-4326-8026-dfba0ca6a881
InvocationID attribute (new value):
d880386d-0385-4171-9ff3-9ab353c029f7
Update sequence number:
6410833

The invocationID is changed when a domain controller is restored from backup media or is configured to host a writeable application directory partition.
