Cant get past my logon after i start Windows XP Please Help

[sinned]

Just finished building a computer for my son.
I installed Windows XP Professional, i have put an icon with his name so he clicks on it after it loads.
Problem is its asking for a password and i never put one in.
When i try to put a password, i get a pop up saying

System cannot log you on due to the following error
The specified domain either does not exist or could not be contacted

I cant even go to control panel i am stuck can anyone please help, thanks

I just Googled your error message and they all point to Active Directory, Domains, LDAP, etc.  During setup did you leave it as a workgroup or domain?

Wish I could be more help

Might be your antivirus package. sounds like the firewall or another third party firewall/security sw is running? are you running an av suite, it may have something running you dont know about.

Before going crazy and trying to figure this out it may be best to do a clean install...
Pay attention to all the prompts in the process.

agreeing with patio here. you have somehow installed the computer as in a domain
