I have Windows 2000 on my home computer and I was messing around with the passwords, trying to figure out how to lock files. Well I think I made it so now there is no administrator. When I try to go in to the "Users and Passwords" part of the control panel it gives me a prompt to "Specify the user name and password of an Administrator on this computer to continute:". I only have one account on it and it won't let me in. Could I have possibly turned off the Adminstrator rights for the only user? How do I log in to adjust anything if there is no administrator?
