What is the best way to gain access when the password is unknown?
If you were provided a computer running Windows 2000 or newer and you have no passwords, what method do you use to gain access with administrator privileges so you can use the system?
Solution 1:
ophcrack is a live cd that boots and brute-forces passwords on a windows machine. http://ophcrack.sourceforge.net/
Solution 2:
ntpasswd will give you off-line access to the registry and allow you to reset or blank passwords, including the Administrator.
