DFS Error : Found 2 <DfsrReplicatedFolderConfig> objects with same ReplicationGroupGuid

After recovering from a crashed virtual server we started getting the following error when checking DFS backlogs ::
Found 2 <DfsrReplicatedFolderConfig> objects with same ReplicationGroupGuid

There are 4 Server 2008 R2 servers connected in a mesh for the DFS structure.  We only get the error when checking the backlogs on 1 of the servers.  The DFS seems to still be in synch and new files are synchronized to all servers constantly.

When you say recovered, you mean you restored the VM ....... in the various ways?

Did you readd the recovered VM back DFS-R group/DFS without removing the old reference???

The virtual servers VHD expanded to the point it filled the physical storage and the server crashed.  We had to run the DFS for 2 days without this server as part of it.  During that time we compressed the VHD file, expanded the storage space and then were able to get the virtual server up and running again.

An MS form searching for objects with same ReplicationGroupGuid
suggesting the use of dfsrdiag pollad.
The suggestion includes going through the system volume information as well as changes/adjustment to a registry key.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Yes we've found the same instructions on multiple sites.  They have not had any impact on the problem.

Can you check whether the DFS-R replication somehow references two connections to or from this system?

i.e. connection
server A to this system
system to server a
system to server A

There should be a GUID of the duplicate.

to which system does that GUID belong.  That may simplify

Difficulty is whether there are files on the recovered VM that have yet to replicate out.

one option is to use robocopy with the /L flag (run through but do not actually copy.

to see if there are files here that need to go look at the staging folder on this VM, and see if there are outsdanding .....

We eventually contacted microsoft and had one of their technicians take a look.
In the end they stopped all DFS services, increased out staging folder size, deleted all replica and volume xml files, deleted associated registry entries and restarted the server.
