After the upgrade of your Windows NT PDC, the Active Directory Installation Wizard fails with:
The operation failed because:
The Directory Service (DS) is missing critical information after installation and cannot proceed. If this is a replica, please rejoin the machine to the domain.
Directory object not found.
After all the objects are created and the security principals are transferred, Active Directory is searched for:
- The Domain object.
- The Administrator account SID.
- The Administrators group.
- The Users group.
At least one of the above objects are missing, causing the failure.
If you upgrade the installation with a slipstream of Service Pack 1 or Service Pack 2, DCpromo will not fail.
NOTE: See Q260941.
