DFS / FRS replication problem with domain-based DFS root targets on single file server
Posted on 2008-11-12
I have been battling with this problem for some time now and I have finally reached the end of the road !
We have a server (Windows 2003 R2 SP1) running DFS. This server hosts a single domain-based DFS namespace with 4 target folders. Of course it was replicating with other DFS servers in our domain orginally but we had replication issues and had to remove the referral partners - so DFS runs only on this one box at the moment.
We have been having issues with this server and we need to do some maintenance work on the box and this will involve some downtime / outage. The problem is that this is a production file and print server so we need to somehow migrate the DFS namespace (or at least the target folders) to a different server "on the fly" whilst the users are still accessing the data.
What we tried to do was create new target folders for each target folder to a different server (which works ok) then enable replication between the original server and the new target folders on the other server. Sound ok ? We thought this would work but the problem is that every time we create the replication group we get this error in the event log:
The DFS Replication service failed to initialize replicated folder F:\Apps because the service detected that one of its private folders overlaps with an existing File Replication service (FRS) replica set. This is an unsupported configuration.
