title: IIS Express Windows Authentication
body: <p>I'm trying to use IIS Express with VS2010 to host a silverlight application.  I modified my applicationhost.config file to allow for modification of the proper configuration settings.  I have the following in my web.config:</p>
  
  <pre><code>&lt;location path=""&gt;
    &lt;system.webServer&gt;
      &lt;security&gt;
        &lt;authentication&gt;
          &lt;anonymousAuthentication enabled="false" /&gt;
          &lt;windowsAuthentication enabled="true" /&gt;
        &lt;/authentication&gt;
      &lt;/security&gt;
    &lt;/system.webServer&gt;
  &lt;/location&gt;
  </code></pre>
  
  <p>I am not being authenticated and my domain service call returns a null record as the user.  I was able to get this to work after installing VS2010 SP1 BETA but I'm trying to get this to work with only IIS Express.</p>
  
  <p>How do I enable Windows Authentication to work with IIS Express.  Is there a configuration setting that I am missing?</p>
