title: ASP.MVC Windows Authentication HTTP Error 401. The requested resource requires user authentication
body: <p>I have an ASP.NET MVC application using windows authentication that I published by visual studio on a windows 2008 server.</p>
  
  <p>But when I try to reach the application from a browser I have to authenticate I get the default authentication form to do this.</p>
  
  <p>If I type my user name and password I can not reach my application but if I use the administration account the application will be displayed in the browser.</p>
  
  <p>And other strange things... in the IIS server I select the application site and click basic settings.</p>
  
  <p>I click on the test connection button I get the following error message:</p>
  
  <p>"Invalid application path".</p>
  
  <p>But if I click the connect as button and use the administration account the test is passed successfully.</p>
  
  <p>Anybody can help me?</p>
