I have a customer running SBS 2003. Two days ago the administrator's password and my password (I am an administrator) mysteriously changed. To do anything on the server I have to log in as another user (also an administrator).
I can go in and reset both my password and the administrator's password but as soon as I lock the computer or log out I can not get back in. It tells me the password is invalid for both me and the administrator. I don't think we have been hacked. From the time I reset the administrator's password to the time I try it and it doesn't work is maybe 15 seconds. Any ideas?
