Recently my sister's pc quit recognizing passwords for all accounts when trying to log on to xp. I tried to run a repair and then access user accounts through the loop hole in install disc but when I did I got error saying xp doesn't recognize user account. I'm still searching net for answers. I don't expect anyone to tell me how to bypass password protection, but maybe direct me in the right direction. Also, what would cause xp to stop recognizing passwords? Thanx.
