The File Replication Service has detected a duplicate connection object between this computer "%7" and a computer named "%1".
This was detected for the following replica set: "%2"
This is not allowed and replication will not occur between these two computers until the duplicate connection objects are removed.
It is possible that this is a transient error due to Active Directory replication delays associated with updating FRS configuration objects. If file replication does not take place after an appropriate waiting time, which could be several hours if cross site Active Directory replication is required, you must manually delete the duplicate connection objects by following the steps below:
 Start the Active Directory Users and Computers Snap-in.
 Click the view button and advanced features to display the system node.
 Click "%3, %4, %5".
 Under "%5" you will see one or more DFS related replica set objects.
Look for the FRS member object "%6" under the subtree for replica set "%2".
 Under "%6" look for duplicate connections from "%1".
 Delete all but one of the connections.
