Please excuse the non HP3K question, We have a couple of NT servers and during the last few days things have gone weird. User Ids are disappearing, User Ids and passwords are out of sync, getting a 'user exists' message while trying to add a user and 'user does not exist' message while trying to delete the same user, etc.. I guess the 'registry' is fouled up. Any ideas on how to recover? Thanks Paul H. Christidis
