So as far as making a clean exit from the host using the tscon 1 /dest:console command...I had an issue with the cmd window being left open and my user on the host end not knowing how/if he should close it.
What I did was make a simple little .bat file two lines:
I named it SessionEnd.bat, you can call it what you want...place it in the HOSTs C:\Windows\system32 folder. Now as you leave the RDC on the host, right click start, click Command Prompt (Admin), in the cmd box type in the name of your batch file (for me SessionEnd.bat), hit enter and you're out of there and the cmd window is closed and the world is good.
