Question : how do I update IIS 6 (SBS 2003) so client certificates will work with Vista and Windows 7?

I have an SBS server set up to require client certificates to use the Remote Web Workplace. Vista does not work with it and I presume that 7 won't either. Does anyone know where and how to get the certificate services update needed for it, and whatever configuration is needed?
