If the Console program does not give the detail you want, I find this program VERY HANDY to have installed on the WHS box.
Install it on your WHS BOX, then remote desktop into your server, fire it up, and it eliminates all the guess work of who is doing WHAT. Shows you the big picture - internal connections to your WHS box and external connections. Very Handy IMO.
Sure beats running around the house of seeing who is doing what inside the house on your WHS box and avoids killing a remote user in a session that they might be doing something productive? :)
