SYMPTOMS

Consider the following scenario.

On a Windows Server 2003-based domain controller, you run an Active Directory domain. Or, you run an Active Directory Application Mode (AD/AM) instance.
You find that some objects are missing. Or, you find that you have incorrect data.
A recent backup contains the missing information about these objects.
You restore the database, and you perform an authoritative restore for these objects.

After the server replicates, you find that objects are still missing from other replicas of the naming context. Or, you find that data for these objects is still incorrect on other replicas of the naming context. However, these objects are not missing on the restored server. Also, the data for these objects is correct on the restored server.

The following events are logged in the Directory Services log on the Windows Server 2003-based domain controller.

Event 1

Event ID : 1173
Category : Internal Processing
Source : NTDS

Message : Internal event: Active Directory has encountered the following exception and associated parameters.

Note In this event, the value of the Internal ID entry may differ slightly depending on the version of the Ntdsa.dll file on the server. Also, the value of the Parameter entry may differ slightly depending on the server replication progress.

CAUSE

This problem occurs when the update sequence number (USN) recalculation yields incorrect results.

After a database restoration, a server changes the replication identity. The server recalculates the USNs that it uses to start the replication process with the existing domain controllers in the forest. Under certain circumstances, the USN recalculation may yield incorrect results. Therefore, the replication does not work.
