This is something which you might wanna read. http://www.petri.co.il/forgot_administrator_password.htm Till this date, I don't think there's any way to legally or actually recover or reset passwords in any system once it's lost. You'll need to reinstall the entire OS if you really wanna legally get into the system to work again.

Hello, the official statement from Microsoft is that without password disk you have to reinstall. As already mentioned from others, there are some available tools and options. Also the password will NEVER reset automatically. Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
