Today Bill Staples announced the following:

I'm attending ZendCon today and giving a demo in the keynote presentation by Andi Gutmans, one of the creators of PHP, and co-founder of Zend.  I am really excited to announce a technical preview release of FastCGI for IIS, a new component for Microsoft's Web server platform.  This release is available immediately for download to Windows Vista, Windows Server codenamed "Longhorn" and previous versions of IIS including IIS 6.0 in Windows 2003 Server and IIS 5.1 in Windows XP.

This announcement coincides with a broader announcement regarding collaboration between Microsoft and Zend to improve performance and stability of PHP on the Windows platform. This effort aims to help PHP developers achieve improved performance on the Windows platform by leveraging the new IIS FastCGI feature together with Zend’s on-going work to improve the PHP engine on Windows. For more information regarding this announcement, see the news release on Zend's site.

Look for IIS in the news today, talking about this announcement.  eWeek.com just posted this news article: http://www.eweek.com/article2/0,1895,2047535,00.asp

This project wouldn't have been possible without a lot of dedicated and hard working people.  The FastCGI feature itself only started development about 6 weeks ago and has come A LONG way in such a short period of time.  Special thanks go to Rick and Wade, Marchel and Cip, and Mike for working long hours, nights, and weekends to prepare the technical preview release now available on iis.net.
