Users "kicked back" to login prompt

[Alan]

I have a very unusual situation on one of my win 2000 pro desktops.
Users who are not members of the Local Administrators group cannot log
in. What happens is that after a user enters proper name/password the
screen goes to blank blue > "Appling individual user settings..." >
then jumps back to the login screen.

I was about to try this FDISK /MBR as refernced here...
http://support.microsoft.com/default.aspx?scid=kb;en-us;249321
....however my symptoms are not entirely identical (since at least some
users can login). That plus I'm wary of using FDISK in general. Also,
renaming/deleting user profile does not work.

Since this only affects non-administrators I have the owner in Local
Admins until I can get this cleared up (not my favorite course of
action but....). I do not want to continue this as a permanent
workaround.

In the meantime I will be updating an NVIDIA driver that another thread
mentions as the culprit.

Thanks for any advice!

Alan:

I think the problem could be that the W2K Pros computers could not contact a
GC in the logon process...

But I'm not shure
