How do you find missling links in a web site using Visual Studio?

I am studying a web site that caught my eye by making a test site privately. Since the original html and CSS and JavaScript code is on a Windows Server and since I am making a test version on a Linux server, there are issues with missing links because of case sensitivity.

Anyway, this is he point. When I load the test website, I get an error message that some file cannot be found, but it does not tell me what file.  It is a very general error message.  Because of the size and all the connections and files, it is difficult to track down what file is missing or misnamed file.  Now, I think there is a way to easily find out exactly what file is not found.  I think there is a way to do this using Visual Studio test classes and projects.  Am I right?
