ASP.NET MVC 2 Routing Errors

After publishing an ASP.NET MVC 2 web application to my schools IIS 7.5 server, I receive a 403 error on initial load and then a 404 error if I try and invoke a route such as /Home/About/Index

I have even tried publishing the default ASP.NET MVC 2 sample application, but with no luck. It appears that the Web Server isn't picking up any of the routes and that it is determining /Home/About/Index to be a directory look-up. Has anyone else experienced similar issues?

I spoke with the system admin and verified that HTTP Redirection and HTTP Errors are enabled. After poking around on, I have seen several comments about routing not working due to the publish location not being a webroot. Any comments on why?

Currently the system admin has the following website directory structure. Could this be the problem?

Default Web Sites

Fall2010

Class123
Class321

Spring2011

I have sought help from the system admin and my professor, however both are unfamiliar with MVC and routing. Any help is appreciated.

Of course, I can just give up on my idea and just use Web Forms and SOAP much like I have done in my other classes, but I would like to learn more about MVC in ASP.NET and REST. Thanks for the help!

Solution

So it looks like the system admin had the app pool to classic mode when it needs to be in integrated. In the default ASP.NET MVC 2 sample application I modified the Global.asax to:

routes.MapRoute(
    "Default",
    "{controller}.aspx/{action}/{id}",
    new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

And navigated to /Home.aspx/About, everything worked fine.

Now I just need to convince our system admin to change to integrated.

EDIT: I was able to get the system admin to switch to integrated. Everything appears to be working fine.
