Workstation Fails to Connect/Sync to Active Directory after Restore


Workstation is unable to successfully connect to or sync to Active Directory after restoring a backup image.


The workstation and server negotiated a new password since the creation of the backup image. When restored, the server does not authenticate the workstation because it's using the old password.


Rejoin the workstation to the domain:

  1. Remove the workstation from the domain by placing it into a workgroup.

  2. Restart the computer, if prompted to do so.

  3. Rejoin the domain.

The above operations can all be performed by right-clicking on My Computer or Computer (depending on the version of Windows) and selecting Properties. Then look in the Computer name section.
