Question : How to remove cached domain user credentials - Workgroup'd XP Pro

We have a Windows 2003 domain (AD).  We have one user who's laptop is not a member of the domain (or any domain for that matter...just with a "workgroup" config).  I do have a user account created for him on the server, so that when he needs to access a network share, he can use his domain user credentials.  The first time he accessed a network location, he put in his credentials and checked the save password box I believe.  Ever since, he never has been prompted to use his credentials again.  How do I force the computer to not save his credentials and force it to ask for them again when he wants to access a network share?

We have a new domain and servers (still W2K3), and even though I kept the same domain name and re-created his same user account and password, all the directory "rights" I have assigned his user do not work.
