Updates that do not change the content of the file are suppressed to prevent unnecessary replication (SL2445)

File Replication Service “prevents” a domain controller from administering the domain because of unnecessary file replication. When Desktop Authority attempts to replicate to the NETLOGON shares of the domain controllers, the replication is rejected because the files being “sent” are identical to the files already there. Errors in the System event log state:

 Updates that do not change the content of the file are suppressed to prevent unnecessary replication traffic. Following are common examples of updates that do not change the contents of the file.

  [1] Overwriting a file with a copy of the same file.
  [2] Setting the same ACLs on a file multiple times.
  [3] Restoring an identical copy of the file over an existing one.
