We recently lost the PDC and it had to be rebuilt. In the process, some of the DFS shares that were hosted there were recreated in the secondary DC and some were used from remote locations while PDC was rebuilt. Now, when users click on their shares they randomly are inaccessible or just "jump" back to the root.
Environment is 5 sites with 6 DCs all running Server 2008 R2. All have DFS and there are some shares that are on all the servers, some are only in select ones. Only users in the site where the PDC was located are having this issue, all other sites seem to be working correctly.
I have verified DNS, error logs and ran the sonar tool but haven't seen anything that can explain this. replication seems to be working fine too.
