I just finished installing windows xp pro, but have yet to reach the desktop
because I am not being allowed to pass the sign-in screen. I made an admin
account on the screen prior, and was not given an option that I know of to
put in a password. However, on the next screen I attempt to fill in my name
and hit enter and it tells me I don't have the correct password. I'd like to
avoid installing windows all over again. The message that it gives me is:
the specified domain either does not exist or could not be contacted. Thanks
in advance.
