I installed the sp4 update last week and now its not takeing the admin password. Unless someone has hacked into the system and changed the password, which I doubt because of all the secuity we have. Has anyone seen this yet on their server and how did you fix it? Also can you tell me if I do the SAM file delete will I loose any data? There are no other user accounts on this server, it is only used for SQL access which is accessed remotly. Will I loose the SQL users?
