Insert your install disk, then hold down the 'C' key while starting up to boot from the installer. Choose your language, and under the 'utilities' menu there should be an option to reset the administrator password.

Find out the password. If you dont have the password or a cd, beware as it could mean the system is stolen goods.

Boot via your OS CD/DVD and reset Master Password then reboot holding down mouse button until CD/DVD ejects.
