Now, what do you mean 'admin is open'? Can you log on as admin? if that's the case go into the control panel, click admin tools-->computer managment-->local users and groups-->users, and then right click admin and change the pass to whatever you like.
If you can't log in as admin then I have no idea what you are saying.
