title: How to determine if the request is coming from a particular windows domain
body: <p>I am developing a web application with MVC-3</p>
  
  <p>I want to give the users of a particular windows domain some special privileges; therefore I have to determine whether the request is coming from that particular domain.</p>
  
  <p>Please note that I am using Forms authentication.</p>
  
  <p>I know that I can do this by tracking the IP address of the user. But <strong>is there a way to directly get the domain name?</strong></p>
  
  <p>For example, if the user is logged in as <code>ADomain\AUsername</code> in a windows machine, is there a way to get <code>ADomain</code>?</p>
