Active Directory Lightweight Directory Services has detected that the replication epoch (as indicated by the msDS-ReplicationEpoch attribute of the following object) of the local domain controller has been changed. This typically occurs as part of the domain rename process. 
 
Object: 
%1 
Old replication epoch: 
%2 
New replication epoch: 
%3 
 
As a result, replication between this domain controller and domain controllers that are using the old replication epoch is no longer allowed. Replication can occur only with those domain controllers using the new replication epoch.
