Registering ASP.net Extensions

In some cases IIS will not install with the ASP.net v2 extension available, and you will have to manually install it and register it with IIS:

>> %windir%\Microsoft.NET\Framework\\aspnet_regiis.exe –i

>> regsvr32 %windir%\Microsoft.NET\Framework\vxxxxxx\aspnet_isapi.dll

Check to see if the extension is allowed in the IIS manager.
