Today the IIS team released the FastCGI Extension 1.5 for IIS 6.0 and IIS 5.1. This allows popular application frameworks that support the FastCGI protocol to be hosted on the IIS web server in a high performing and reliable way. FastCGI provides an alternative to the Common Gateway Interface (CGI), a standard way of interfacing external applications with Web servers that has been part of IIS since it’s very first release.

All the details, including how to install can be found at Ruslan’s IIS blog here:
