title: IISExpress returns a 503 error from remote machines
body: <p>I'm attempting to test a website I have running in a local IISExpress instance with some other machines / devices on my local network.  I am running Win7 Pro.</p>
  
  <p>When I first attempt to browse to my machine from another machine on my local network segment, I get a 400 error: Hostname is invalid.</p>
  
  <p>I understand that I need to grant remote access to the ACL with a command on the elevated command prompt like:</p>
  
  <p><code>netsh http add urlacl url=http://mymachinename:50333/ user=everyone</code></p>
  
  <p>Now I get a 503 service is unavailable error.  </p>
  
  <p>Windows Firewall is currently shut off, and I am able to browse my local IISExpress instance with the address <code>http://localhost:50333</code></p>
  
  <p>What is the final piece to this configuration puzzle?</p>
