title: Windows 8 simulator doesn't work
body: <p>The Windows 8 simulator which comes with Visual Studio 2012 does not launch either via debugging in Visual Studio or by running it directly. </p>
  
  <p>As the simulator used remote desktop (RDP) and the issue occurs within Visual Studio &amp; if I start it directly. I have identified that if my VPN is NOT enabled, then the simulator works fine. Thus I believe the issue is between VPN &amp; RDP.</p>
  
  <p>In the event log for RDP (<code>Application and service logs</code> - <code>Microsoft</code> - <code>Window</code>s - <code>TerminalServices-RDPClient</code>) I see the following message:</p>
  
  <blockquote>
    <p>RDP ClientActiveX has been disconnected (Reason= 5639)</p>
  </blockquote>
  
  <p>Reason 5639 is <code>The policy does not support delegation of credentials to the target server.</code></p>
  
  <p>Are there any policies in group policy that I can change to enable delegation of credentials?  </p>
  
  <p>I have also tried turning off the firewall, setting RDP to all users and running the simulator as administrator but none of those options have helped.</p>
