BIOS and its password. (part 2)

Changed the CMOS jumper and reset the CMOS. So Windows 2000 boots up, Asks for me to put in a password for the last user which was "student". So i tried a blank password, and it didnt work, next I did student, it worked. Then used mmc (Microsoft Management Console) to check users names on the computer, saw Administrator and logged off of student, tried Administrator with a blank password, what do ya know it worked. So now im in and the job is done. I shall contact the owner and let them know the good news for them, and see if theres any thing else they want done.
