I followed the same procedure with TS in Admin mode and I was able to
terminate my session by closing TS Client. I then logged in again and was
able to Kill the CMD.EXE session that was still running from my prior
TSClient session. It didn't require me to reboot.

I've verified this to work on Win2K Pro SP2. It took 3 F7s and my system
hard-booted as if I had hit the reset button.

On a Win2K Server SP2 on a terminal session (administrator mode) it doesn't
crash the box. However:
 - You can create a "cmd.exe" session that is unkillable
 - You can't log off that session
 - You can't kill that session or "cmd.exe" process from the console
 - You can't log the user off from Terminal Services Manager
 - You can't create another instance of "cmd.exe" in that terminal session
 - A reboot is required to kill the session.

Hello, this is a new bug found in W2K in all flavors, works with all levels
of users.
Here is the proof of concept:
Open a Cmd Window
Ping to any host (for example ping preferred a host in your LAN),
no switch needed. Just ping
Now press F7 and Enter (try a couple of times quickly...less than ten , and
you can see what a meaning)
The machine reboots, from nothing a warm reboot.
Please let me know if you have the same bug. I tried this in W2k sp2 English
and Spanish.
