Clear remembered passwords in XP

Ok this is bit of a weird one. I need to clear all of the passwords that I have asked Windows XP to remember. The catch is....I don't have admin rights on this PC!

I entered a password and username to access a server, and unfortunately have found out that I do not have access to this server. Being all efficient, I clicked "remember password". Now whenever I try to get to the server location, I'm am not given the option to enter a new username or password!

Try going to Start -> Control Panel -> User Accounts. For computers on a domain, click the Advanced Tab and click Manage Passwords. For a stand-alone computer, when you get into User Accounts, click your user account and click Manage My Network Passwords found on the left pane.
