title: IIS 7.5 Invalid authentication headers 401.2 when viewing site in browser
body: <p>I have a Visual Studio 2010 project that is using Forms Authentiation.  It runs fine from within Cassini (visual studio systray IIS, aka pressing F5).  I'm using MVC2.</p>
  
  <ol>
  <li>I created a website in IIS 7.5 (on my Windows 7 machine)</li>
  <li>then pointed the physical directory at my Visual Studio project file</li>
  <li>Enabled only Forms Authentication in IIS</li>
  </ol>
  
  <p>Keep receiving this error:</p>
  
  <p>HTTP Error 401.2 - Unauthorized
  You are not authorized to view this page due to invalid authentication headers.</p>
  
  <p>PS:  I didn't use the Create Virtual Directory option in Visual studio, since I need host headers for what i'm doing, so a dedicated IIS website.</p>
