See who is logged onto a computer, either locally or remotely

Syntax
      psloggedon [- ] [-l] [-x] [\\computer | username]

Options:

   computer   The computer on which the process is running. Default=local system 

   -l         Show only local logons instead of both local and network resource logons.

   -x         Don't show logon times.

   username   Search the network for computers to which that user is loggedon.

   -          Help, display all options and units of measurement used.

PsLoggedOn's definition of a locally logged on user is one that has their profile loaded into the Registry.

Note that PsLoggedOn will show you as logged on via resource share to remote computers that you query because a logon is required for PsLoggedOn to access the Registry of a remote system.
