Changing Network Password in XP

I have 3 computers on my network. I made it so that one of them required a user name and password in order for the other 2 to be able to access it over the network. Now I want to change that password, and I've forgotten how I set it up in the first place.

Anyone have any idea how to setup or change network user names and passwords in XP?

anyone??? this should be an easy one for people here!

log on as administrator.

right click "My computer", select Manage. Then go to local users/groups. find the user you want to change the password of, and choose "set password".

I believe that is what you are asking for?
