FileMaker 11 Server - Installation Issues with IWP & IIS

Your post

Installation completes with no errors, but no "FMI" website is ever created.  The IIS Default Web Settings are changed to a non-existent version of ASP.NET.  I can change the website back to 2.0 and run the Adsutil command to run IIS as 32 bit and I can bring up the websites, otherwise after the IWP install it shuts down IIS with "Service Unavailable".


ENVIRONMENT:  2003 Windows SP2, AMd 64 bit, 2.93 GHz, Dedicated server, IIS 6.0
