Student Mandatory Profile/Default Profile Issue
I'm at the point of offering a bounty for a solution to this...
We have students set up using a single shared mandatory profile, and all lab computers use Deep Freeze. We have recently had one school that has been experiencing students getting the default profile rather than the student profile.
In testing we've found the initial login on a clean recently rebooted PC (XP SP3) works fine. Then if we log out and log back in right away we get the following error:
Windows cannot copy file \\<server>\studentprofile\Cookies\index.dat to location C:\Documents and Settings\<Student.Name>\Cookies\index.dat. Possible causes of this error include network problems or insufficient security rights. If this problem persists, contact your network administrator.
DETAIL - The process cannot access the file because it is being used by another process.
Logged as Event ID: 1509
They are then logged in with the default system profile which means no GPO, etc. so they have access to command prompt, control panel items, etc. essentially a local admin account.
The student profile has not been changed in any way, nobody has any write permissions to it - strictly read only. All date stamps on the profile objects are evidence. Permissions are fine - as again indicated when the initial login works without issue.
Something somewhere is hanging onto that .dat file and we can't figure out how to resolve it.
If anyone has seen this before and has any idea of what might be causing it, please let me know.
