Okay, so I'm going to a LAN tomorrow and decided I should clean up the **** on my computer, so I re-installed Windows. The installation went normal, but when I try to log in, it already has a password set up. The password doesn't matter, though, because whenever I try to log in, it gives me generic error box with something along the lines of:

"Your computer could not log you in because the domain name doesn't exist. Contact admin etc."

I have no clue what to do. If it has anything to do with it (doubtful), I tried to make an un-attended installation, but got bored and played BF1942. So I ended up just using Gateway CD. Please help, if I don't figure it out by tomorrow, gonna have to take this **** computer (probally can't even run CS1 on here).

Hi there...simple fix

When logging on - click on the 'options' button...this should give you a 3rd option.

Change it from whatever it is on to "This Computer"
Should fix you right up.
