Joining a Windows Vista Business Desktop Client to Small Business Server 2003

Spent most of today trying to get a Vista desktop to join an SBS 2003 server. Most of the time was wasted trying to get SP2 on the machine which did not seem to be properly installed. This is a pre-requisite to installing the various patchs found here on the SBS 2003 server. This page leads in nicely to all the supported combinations of clients and servers.
