edit:
because it a MVC site, the default document doesn't apply. check the following steps:
- IIS Extension Less URLs are enabled and allowed.
- ASP.NET 4.0 is installed and registered.
C:\Windows\Microsoft.NET\Framework\<version>
and thenaspnet_regiis -i
(this will typically force IIS to use the MVC infrastructure instead of using the default document methodology) - Ensure App Pool is in 4.0 Integrated mode.
- Ensue that the IIS Advanced Settings for the website are showing the right root folder path.
