Unwanted Profiles

I am looking at running a vb script at startup to delete all profiles on a machine except Administrator, All Users, Default User, and 2 custom user accounts (user and oasdguest). Anyone have any ideas? Basically, when the login screen comes up, the only user profiles I want to exist are Administrator, All Users, Default User, user, and oasdguest.

I am running Windows XP SP2 Professional in a Windows Server 2003 domain.

I have been looking online for quite awhile, but have had no luck.

Thanks.
