Denying the local Administrator and user accounts the ability to log on locally was a bad but not irreparable move. To fix this problem, you'll need to connect your computer to a network. Then, you need to connect to it remotely by using the Microsoft Management Console with the Group Policy snap-in. From there, you can give the local Administrator and other accounts permission to log on to the computer locally. If you've never done this type of thing before, I suggest that you get someone who works in the IT business to help you.
