How do I run windows 32bit applications in IIS on Windows XP 64 bit?
Note: This is not running within Visual Studio. Note: Only 404 errors are logged. Note: 404 errors caused by IIS disabling CGI scripts
You're probably having a Bitness issue - after you do the Enable32BitAppOnWin64 script, you need to register the 32 bit versions of the ASP.Net filters. Go to the 32 bit version of the framework (C:\Windows\Microsoft.NET\Framework\v2.0.50727) and re-run the aspnet_regiis.exe -i -enable command.
