title: Using Windows Authentication, not getting a popup
body: <p>In my program, I'm attempting to use Windows Authentication, which I have never used before and so am pretty confused. I've followed what I think I should do and what I've found in my google searches by adding this in my <code>Web.config</code>:</p>
  
  <pre><code>&lt;authentication mode="Windows" /&gt;
  
  &lt;authorization&gt;
    &lt;deny users="?"/&gt;
  &lt;/authorization&gt;
  </code></pre>
  
  <p>and my IIS settings look like this:</p>
  
  <p><a href="https://i.stack.imgur.com/ZHeYJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZHeYJ.png" alt="enter image description here"></a></p>
  
  <p>but whenever I run my website, it just loads up correctly when I believe I should be getting a popup that asks for my username/password. How can I fix this? Thanks</p>
