title: Visual Studio Development Server (2010) and NTLM authorization
body: <p>I'm using Visual Studio Development Server (Visual Basic 2010) and it works fine. Now I've enabled NTLM Authorization because I want to test the website using a different user account. Now when I try to access the website I always get the following error page:</p>
  
  <h2>Server Error in '/' Application.</h2>
  
  <p>HTTP Error 403 - Forbidden. </p>
  
  <hr>
  
  <p>Version Information: ASP.NET Development Server 10.0.0.0 </p>
  
  <p>I'm using a test account which is a normal user within our domain. I've already set the access rights in my project folder to Full Access for this user but it does not help. Any further ideas?
  Thanks!</p>
