psexec from terminal

v6.3.0.6 on host and viewer.
windows 7 on both (all three).

I am trying to log into HOST_1 in the Viewer, and start Remote Utilities 'terminal'. From that command prompt, use 'psexec' to start cmd.exe on the HOST_2. Then execute cmd.exe command line commands on HOST_2. In my case, HOST_1 and HOST_2 are on the same LAN. I am remote to that LAN.

(psexec is part of the popular sysinternals utilities from Microsoft. I'm using v2.11.)

One more note, same user login on both computers on remote LAN. Also of note, this user has no password, which can make a difference.

But first, I know it should work, because if I use Remote Utilities to connect to the desktop of HOST_1 and use regular cmd.exe started from the remote desktop on HOST_1 and run psexec in there, it works fine. Here's a log:

Success!

But, when I use Remote Utilities 'Terminal' to connect to the same HOST_1 and do the exact same thing, it doesnt work. It appears to connect, then exit immediately with "code 0" which I believe means no error. In other words, it doesnt attach the input stream (my keyboard typing) to the HOST_2 cmd.exe so I can type commands.

Note: I am doing File -> Current User because doing it as the 'system' account has other problems. You can see the change in the log:

Hello John ,

I asked our development about this. Unfortunately, due to some technical reasons in the Terminal mode we cannot exactly replicate how windows cmd works.
