  <p>The question <a href="https://stackoverflow.com/questions/124967/getting-logged-on-users-name-with-or-without-domain-in-windows">"Getting logged on user’s name with or without domain in Windows"</a> comes close, only I want to find the opposite.</p>
  
  <p>I ask about the possibility due to my lack of knowledge concerning the internals of Active Directory. My gut feeling is that Active Directory only knows when (and possibly where) a domain user was last authenticated, and doesn't track current sessions or log-offs.</p>
  
  <p>Any language that provides this solution will be an acceptable answer, but a .NET solution is preferred. More importantly, I'd like to know if this is even possible.</p>
