Copying verbatim from another blog since there were no resolution for it.
"After setting up the DFS root I was unable to access the files on the original server (FS_1). Upon pinging FS_1 I receieved a reply from the IP address of the DFS Root box (DFS_1). I logged into my DNS servers and changed the A Record back to the original IP address of FS_1. Now the problem is that about every 12-24 hours the A Record on the DNS servers reverts back to the IP Address of the DFS Root (DFS_1). I've removed all DFS root entires and cannot seem to figure out just what would be casuing the IP Address to keep reverting to the IP of the DFS Root... any ideas?"
I am in the same situation with my environment. DFS namespace were removed from the source servers since it did not work as intended. All DNS reference to IP of DFS server have been removed from DNS and replicated down. Every so often the IP for the source server would revert back to the DFS root server IP. I can't seem to pinpoint what process keeps renaming the IP.
