Option 1

event id error 1988

1. In the Event ID you will see the following information…

Source DC (Transport-specific network address):
CN=926e60b0-13d9-447d-bff6-70334e598823�ADEL:dc784939-66f9-4433-9830-28fd0f965736,CN=Deleted Objects,CN=Configuration,DC=domaina,DC=com
Object GUID:

The only info you need from that is the GUID of the source domain controller, in the example above that’s 9160d4ef-7d65-45fd-aa8e-624acff91688 also take note of the domain “DC=domaina,DC=com“.

Event Source: NTDS Replication
Event Category: Replication

repadmin /removelingeringobjects SERVER01 9160d4ef-7d65-45fd-aa8e-624acff91688 DC=domaina,DC=com /advisory_mode

IMPORTANT: If either server is Windows Server 2000 this won’t work! You need to do this instead.
