Hi. We have problem from time to time when login to the computer (XP)

Client 4.83, 4.90 and 4.91 has the same problem. We login to NW and a local
user on the computers.
The error is "local profile not found, using a default profile". If we turn
off the
computer, the next login is ok. (sometimes happens 2 times before ok)

Anybody know how to solve this problem ??
