  </ol>
  
  <p>And a few youtube videos.</p>
  
  <p>I am stuck fast in a certain point. When I am told in Central Admin to click <strong>"Site Actions > Site Settings > Application Management > Manage Applications > SharePoint - 80"</strong> I do this. My next step is to click <strong>"Authentication Providers".</strong></p>
  
  <p>In my system this option is 'Greyed out' and not selectable. I also try to click <strong>"Anonymous Policy"</strong>. The options in this section are also not selectable.</p>
  
  <p>Is there further config needed? Can anyone suggest a possible solution? or link an article with the solution? The mix videos leave this config out.</p>
  
  <p>Thanks in advance</p>
