Active Directory encountered a replication error. Replication will be delayed.

Active_Directory_encountered_a_replication_error.__Replication_will_be_delayed._5_Rule (Rule)

Knowledge Base article:

Summary

The Active Directory® directory service encountered a replication error because a new crossRef object was added to the forest with the same name as a local directory partition. The crossRef object cannot be added until the conflicting local directory partition is removed.

Sample Event:

Active Directory encountered a replication error because a new crossRef object was added to the forest with the same name as a local directory partition. Local directory partition: %1 The crossRef object cannot be added until the conflicting local directory partition is removed. This usually occurs when a crossRef object has been deleted and recreated rapidly on the domain naming master, and the changes have been replicated. The error occurs because the Knowledge Consistency Checker (KCC) has not yet had a chance to remove the local directory partition. This situation will correct itself when the KCC finishes removing the partition, but replication may be delayed.

Causes

This usually occurs when a crossRef object has been deleted and recreated rapidly on the domain naming operations master and the changes have been replicated. The error occurs because the Knowledge Consistency Checker (KCC) has not yet had a chance to remove the local directory partition.

Resolutions

This situation will correct itself when the Knowledge Consistency Checker (KCC) finishes removing the partition, but replication may be delayed. You can resolve this conflict by deleting the newly created crossRef object and creating it again after the local directory partition has been removed from the forest.
