Maybe you can try safe mode.I found this LINK,it may help.
I recently did a clean install of Windows XP, and everything works fine, I get to the log on screen where it says administrator and I clikc on the icon to log on and I ge the following error:
" SYstem Cannot log on due to the following error. The Specified domain either does not exist or could not be contacted. Please try again or consult your system administrator"
anybody know why and/or what I can do?
