title: Error 500 in a ASP.NET MVC Application running on IIS 5 + Windows Server 2003
body: <p>My page has an Ajax.BeginForm helper and when I submit this form, in localhost, I have success but, when I run the same page and try to submit my page on the server (Windows Server 2003 + IIS 5.0) I have a 500 Error.
  Somebody know why this happens and how can I solve this problem?</p>
  
  <p>Thanks.</p>
