title: IIS 7.5 - Erro HTTP 401.0 - Unauthorized
body: <p>I have a Application in Asp.net MVC running perfectly in Visual Studio 2015, with IIS EXPRESS (local computer).</p>
  
  <p>I try execute this application in other computer (Windows Server 2008 R2 w/ IIS 7.5). I did a Deploy and i put in folder "C:\inetpub\wwwroot\testsite".</p>
  
  <p>On execute localhost/testsite, the index page showying normaly, but, on submit the form (it's a login page), my IIS presents the "401.0 ERROR".</p>
  
  <p>I am using "authentication mode forms":</p>
  
  <pre><code>&lt;system.web&gt;
      &lt;compilation debug="true" targetFramework="4.5.2" /&gt;
      &lt;httpRuntime targetFramework="4.5.2" /&gt;
      &lt;authentication mode="Forms"&gt;
          &lt;forms loginUrl="~/User/Login" timeout="2880" /&gt;
      &lt;/authentication&gt;
  &lt;/system.web&gt;
  </code></pre>
  
  <p>Pool application is "DefaultAppPool". The Authentication: "Anonymous = ON", "Forms = ON", others options = OFF.</p>
