title: WCF Access is denied with IIS
body: <p>I created a brand new WCF web application with .NET 4.5.1</p>
  
  <p>I have set in IIS the Authentication to Anonymous Authentication (enabled). All the other options are disabled. The web site in IIS is set to its own application pool which run under my credential. I am the administrator of the machine. The application pool is set to use version 4.</p>
  
  <p>The url is </p>
  
  <pre><code>http://localhost:8885/Service1.svc 
  </code></pre>
  
  <p>The port is good.</p>
  
  <p>If I use the Process Monitoring I see this output for w3wp.exe:</p>

  <p>Why do I get a 401 error, if I have the read-write access (the app pool is running my account)?</p>
  
  <p>Server Error in '/' Application.
