Can ASP.NET MVC routing configuration failures contribute to an HTTP Error 403.14 Forbidden?

Yes, indirectly, ASP.NET MVC routing configuration failures can contribute to a 403.14 error. If the MVC application's routing isn't correctly set up (e.g., missing default routes, incorrect route patterns, or the `UrlRoutingModule` not being properly registered in IIS/web.config), the MVC framework might fail to intercept and handle the incoming URL. In such cases, IIS will then attempt to process the request as a static file or directory request. If the URL corresponds to a physical directory on the server and directory browsing is disabled (the default and recommended setting), IIS will return an HTTP Error 403.14.
