How to launch an application on remote pc with Radmin?

Is it possible to launch a program or batch file on a remote pc (using
Radmin) from a telnet session? If not, is there another way to do this in
radmin 2.0 without starting a remote desktop (full control) session? I want
the application to run on the remote PC not the local one....

The reason I ask is because I want to trigger/start a pop up message box
(like the net send command) that will appear on the remote pc. The remote
PC is not on the local LAN, but is on a WAN connection (over the net). I
have renote admin set up and is working well, but don't know if its possible
to make a message pop up using radmin 2.0

Any advice on how to acheive this would be very welcomed...

Thanks a lot....
