title: Visual Studio IIS HTTP 503 Service Unavailable
body: <p>I have searched every topic and it seems that everyone got there problem solved already and I have tried all the possible solution they have provided or I am still missing something.</p>
  <ul>
  <li>FireWall already turned off.</li>
  </ul>
  <p>Ok so I am trying to access my IIS server Application that is currently run by VS 2013. Update 2.</p>
  <p>when I try to access http://localhost:29790/ &lt;- this to <a href="http://192.168.1.3:29790" rel="nofollow noreferrer">http://192.168.1.3:29790</a> which is my current IP on my local. It gives me 503 error.</p>
  <p>I have searched for the solution and gives my a tons of.</p>
  <p>applicationhost.config file</p>
  <pre class="lang-xml prettyprint-override"><code>&lt;site name=&quot;SMApplication(4)&quot; id=&quot;10&quot;&gt;
      &lt;application path=&quot;/&quot; applicationPool=&quot;Clr4IntegratedAppPool&quot;&gt;
          &lt;virtualDirectory path=&quot;/&quot; physicalPath=&quot;C:\Users\DanZe3\Documents\Visual Studio 2013\Projects\SMApplication\SMApplication&quot; /&gt;
      &lt;/application&gt;
      &lt;bindings&gt;
          &lt;binding protocol=&quot;http&quot; bindingInformation=&quot;*:29790:localhost&quot; /&gt;
      &lt;/bindings&gt;
  &lt;/site&gt;
  </code></pre>
  <p>I have tried this.</p>
  <ul>
  <li><code>*:29790:*</code></li>
  <li><code>*:29790:</code></li>
  <li><code>:29790:</code></li>
  </ul>
  <p>by chaining the bindings. But it is still not working. I restart the PC or the VS as well. But the problem is, when I try to re-open VS. VS overwrite the <em>applicationHost.config</em> and add another binding.</p>
  <p>As you can see in my site named &quot;SMApplication(4)&quot;  (It has made 4 already!) This is automatic when I re-open the file
  and then the bindings will be <code>*:29790:localhost</code> again.</p>
  <p>Somehow Editing this bindings. Visual Studio will create another binding of the application, having another site named SMApplication(5).</p>
  <p>I have tried to remove the localhost on the <code>*:29790:localhost</code>, but when I run the application it gives me.</p>
