title: IIS Windows Authentication 401 UnAuthorized
body: <p>I've a sub-application that I want to use windows authentication.
  I want that login box pops up even in the domain when the person first reaches the page.</p>
  
  <p>When I turn off Kernel-mode authentication, the login box pops up, but fails with error 401 Not Authorized after 3 login attempts.
  If I turn this on, It doesn't even asks for the password,I believe this is due the computer is in the servers domain and the credentials are passed automatically. </p>
  
  <p>Is there any possibility to show login form for all users, including domain users?</p>
  
  <p>In the image below are my server configs. </p>
