ZoneWalker its clear to me now, the secret Administrator account you speak of does not show up on the logon screen no, but when you goto administrative tools and computer management and then users it is shown. This is the same as the control userpasswords 2 control popup window. Which does show every account on the box. The administrator account which you renamed, is this the secret account which you speak of?
If so then I still stick by every word which I say because they reference that account. Or is there another account which you speak of that you have just failed to mention the name of?
