I deployed two file servers and set up DFS with replication. I use several domain-based shares. The clients in my organization have their folders (desktop, My Documents) redirected to the shares. A few users have a recurring problem, though. Occasionally they will log in and try to open files in their My Documents folder and they will only open as "read-only." They also are not allowed to create new documents within their My Documents folder.
.
I found the reason this happens: when the user logs off their computer, the DFS server they were connected to does not close their session. If I connect to the server and open "Computer Management" console and look at Shared Folders --> Sessions I can see the user still listed. If they log back in and happen to get directed to a different DFS server in the group, this is when the files open as read-only. I can fix the problem in a couple ways: I can either close the open sessions on both servers and have the user log back in, or I can open the My Documents folder on the user's computer, right-click any folder, select the DFS tab, and set the server with the open session to "Active."
.
As I mentioned, this problem only affects a few users so far in the entire organization. Has anyone seen this issue or have any ideas on how to prevent it from happening?
