Scenario

You use a Windows Server system like 2008 R2 and DFS shares on 2 or more servers, and they suddenly do not stay in sync any more.

In Windows Event Log, you see remaining events 2212 and 2104, source DFSR.

The DFS replication database seems to be damaged.

Solution

  1. Log in to your server where the events are appearing.
  2. Stop DFS Replication Service (e.g. “net stop DFSR” or via services.msc)
  3. In Explorer, go to your drive which contains the DFS directory, and give yourself full access to [yourdrive]:\System Volume Information (right click -> Properties -> Security tab).
  4. Step into System Volume Information folder and try to move DFSR dir out of it. If it does not work open “cmd” (maybe with Admin permissions) and move DFSR out with a command like “mv DFSR ..\temp”.
  5. Restart DFSR service, DFSR folder should be recreated. As you see in Windows Event Log, it might take a couple of hours for DFS to be in sync again.
