Locked out because i changed domain?

[Luke1445]

Hi
My name is Luke Morrison and i have a toshiba TE2100 laptop runnig Windows XP Pro (factory installed with my school) i graduated last year and hence changed the domain for a home network. i was asked for the administrator or the (someone who has authority to do this) password so i put in my admin password and all was good. on the restart i was locked out of logging in to the admin with the same password as i used for the domain change.

How do i log back in again?. And if worse comes to worse what can be done?
Thankyou Luke

Once you remove the computer from the domain, all domain user accounts are unusable (until you join the domain again). You can log in to the laptop as the local administrator of course.

Ask the password from whoever installed Windows. There are also free utilities out there that can reset Windows passwords.
