title: Find computer name by username (check where the user is logon to)
body: <p>I built a windows form application that receive IP and represents the computer name and the opposite.</p>
  
  <p>However, I don't know if it's possible to enter username, and then recieve the IP or the computer name that the user is login to (if he login). </p>
  
  <p>Loop through all the computers in the domain is not an option to me because it will takes so long. Any suggestions?</p>
