Roaming Profiles - Locked UsrClass.dat

C

Charlie Hill

I am using romaing profiles with my terminal clients.
Group policies are set to delete cached profiles after a
user logs off.
Somtimes a profile is not deleted, Instead, the profile
can't be deleted unless the host server is rebooted. If I
try to manually delete the profile, I get an error message
saying that it can't delete USRCLASS.DAT due to a sharing
violation.
The user can not log back on due to a access denied error.
Event 1000 is recorded in the event viewer.

EventID 1000 (with source Userenv, I presume?) is a very common
one. Have a look here for a large number of causes and possible
solutions:

Additional hotfixes for this issues (that haven't made it yet to
EventID.net):
