title: Enabling windows authentication in IIS
body: <p>I am on vista home premium (32 bit) and I need to enable windows authentication for IIS because the Sitefinity sample site returns a 401. However, in add windows features, there is no sign of windows authentication despite having expanded all the treeviews.</p>
  
  <p>How can I enable windows auth?</p>
  
  <p>Thanks</p>
