I don't know if you have tried it.
Remove the current login user in 2003, the system will not prompt "The current user is using, can not delete" and other information. I tried it, after deleting, as long as you don't quit, you can also use this user. See what you think here? If you only have one user in your 2003, when you have finished the service you want to open, then remove this user, as long as you don't quit the system, your server security problem doesn't know if it can improve. . I didn't tried it behind, but I reloaded the system in front. The friend who is not afraid to reload can try the situation behind. Oh, but the consequences are paid.
