Andy Leonard is working on a series of articles that present a visual guide to installing Team Foundation Server (currently for the December 2005 CTP) in a single-server deployment in a Virtual PC from the ground up. You may recall that Dave Bost wrote an article for doing this with the December 2004 CTP. He even includes all the steps for creating the virtual machine image and configuring the server as a domain controller. When I last checked, he had posted everything up to installing IIS. Andy says he’ll likely have the final articles posted by the beginning of the new year. Go check out his site (free registration required).
Update: I got word from Andy - all of the articles are now available online.
