I delivered a webcast on April 23rd covering Windows Server 2008 and PHP that includes a step-by-step demonstration on configuring and testing PHP on Windows Server 2008 as well as integrating PHP with .NET services in IIS 7.  Here is the event overview:

Windows Server® 2008 featuring Internet Information Services 7.0 is a powerful Web application and services platform that delivers rich Web-based experiences.  With the addition of FastCGI support, it is now possible to run PHP applications in a fast and stable manner in IIS.  In this session, learn how to configure FastCGI and run PHP applications on IIS 7.  In addition, see demonstrations during this webcast that highlight how a PHP application can take advantage of other services available in IIS 7.
