We have a network with one domain controller running windows 2003 r2 and active directory in 2003 r2 mode. We had an issue where users Documents folders were being written to the root of the share userdata$/Documents instead of userdata$/username/Documents which was caused by a typo in the redirect group policy.
Since we fixed this the dfs and corresponding lshash takes up all the remaining CPU. Disabling the service also breaks the group policy editor. Upon restarting the service it quickly go es back to consuming all available CPU which causes a plethora of network problems for domain users including logging in and printing.
I have tried deleting the offending and duplicate "Documents" folders under userdata$ but the problem persists. The server is up to data with sp2 and subsequent patches and has been rebooted several times.
Any thoughts as to what could be causing this issue or a solution? Thanks!
