2K8 DFSR Replication not working

Question

We moved from 2003 servers to 2008 servers a few months ago, recently we noticed that replication between server1 & server2 is not working, as the initial copy from the primary to the secondary semed ok, but nothing has replicated since. When you run
the health diagnostics in DFS it appears to indicate no issue and all is ok, but nothing is actually replicating from 1 to 2.
when i run dfsrsdiag backlog on either server says there's nothing in backlog. I have a feeling it might have never worked since the initail copy, but found another utility which shows me the below, what does this mean? replciation should be one way server1
to server2
UPDATE:
Dfsradmin Membership List /RGname:Rep_group_namef/attr:MemName,RFName,IsPrimary
Both servers show No to Primary, is this absolutely required? as other servsr with DFS shares have this option of no for all mebers but they are replicating OK

Answer 1

Hi,
If initial replicaiton is finished, it is common that there is no primary server.
Here are the steps to clear database and redo the initial replication. You could first test the step 8 only to see if it could help. If not then try the clear database steps.
1.       Stop and ALSO disable the DFSR service on <ServerA> server (don't just simply stop it)
2.       In Windows Explorer open the specific drive
3.       Right click on the "System Volume Information" directory and select Properties\Security
Note: You might need to select the option for "Show hidden files, folders or drives" and also uncheck "Hide protected operating system files" in the folders view options to be able to even see the "System Volume Information" directory.
4.       Grant your user account that you're logged in with (if a member of Administrators group this will also suffice) "Full Control" to the "System Volume Information" directory.
Note: You may get an error on setting security on some files - this is expected.
5.       Open an elevated/Administrative command prompt. Switch to the "<drive letter>:\System Volume Information" directory
6.       Type the command "rmdir DFSR /s"
7.       Enable and re-start the DFSR service on <ServerA> server
8.       We will then set the <ServerA> server as the Primary member with dfsradmin.exe utility –
Dfsradmin Membership Set /RGName:<RG Name> /RFName:<RF Name> /MemName:<Member Name> /IsPrimary:True
Note: Files will be replicated from ServerA to all other targets. So if there is any newer file on other target servers, backup before starting replication.
