Ok a buddy of mine had an internet cafe that he just recently sold. He ended up selling all of his computers aswell. I picked up 2 of them. They are windows 2000 SP4. Now on one machine i know an admin account and password but not for the other. The other has the 2 default accounts administrator and guest. Since it automatically logs into the admin account i never questioned what the password was. Now I need it for networking purposes. So i can log into the admin account but i dont know the password. So is there a way to reset the password without knowing the previous password or better yet just recover the lost password without changing it? Any help?

yah, fromat the entire hd
