title: In IIS, why doesn't Window Authentication show up as one of the options for my web application?
body: <p>I'm reading about <a href="http://www.asp.net/mvc/tutorials/authenticating-users-with-windows-authentication-cs" rel="noreferrer">how to set up windows authentication for my web application on IIS 7</a>. In the description they have Window Authentication as an option in IIS.

  <p>I have windows authenication turned on for my machine(I'm on Windows 7 Professional 64bit) and I  still don't see it as one of the authentication options for my web application. Why?<br>
