I have a lab of Windows XP SP3 computers on a domain. Occasionally, students logging in are greeted with the message...
Windows cannot load the locally stored profile. Possible causes of this error include insufficient security rights or a corrupt local profile. If this problem persists, contact your network administrator.
Followed immediately by...
Windows cannot find the local profile and is logging you on with a temporary profile. Changes to your profile will be lost when you log off.
This affects most (but not necessarily all) domain users of that computer until the computer is restarted, at which point their profiles become accessible again.
We are not using roaming profiles.
A search for NTUSER.DAT in Process Explorer on an affected machine reports that the System process is locking NTUSER.DAT files for multiple users, including users that have not recently logged on:
Process PID Type Handle or DLL System 4 Handle C:\Documents and Settings\Administrator\NTUSER.DAT System 4 Handle C:\Documents and Settings\TEMP.(domain)\NTUSER.DAT System 4 Handle C:\Documents and Settings\(user 1)\NTUSER.DAT System 4 Handle C:\Documents and Settings\(user 2)\NTUSER.DAT System 4 Handle C:\Documents and Settings\(user 3)\NTUSER.DAT System 4 Handle C:\Documents and Settings\(user 4)\NTUSER.DAT
I have encountered this problem when running no antivirus software, Symantec Endpoint Protection, even Microsoft Security Essentials, so it does not seem to be antivirus-related.
This does not seem to happen anywhere else on site. Possibly related info: the computers are rebooted infrequently, typically entering standby mode when not in use; the specific computers in question are Lenovo A58 desktop towers.
