Why is it so difficult to figure out the URL?

I have an MVC app hosted on one of our servers on IIS 7.

I have WCF service (dll) hosted on one of our servers on IIS 7 in that web app. The omxDB.svc file is in the bin folder of the web app, as is the dll. The service configuration is in the web.config of the app (parent folder of the bin folder). The contents of the .svc file is: <% @ServiceHost Service="omxDB_AppLogic.DB" %>

The url of the app is http://mwnecmq02/beispiel

I expect the url of the service to be http://mwnecmq02/beispiel/omxDB.svc but when I put that in my browser I get a 404 error instead of the service information page I expected.

How do I figure the correct url?

Thanks,
