ok. can you run this command successfully from the ACCTUAL machine? i
mean, without ssh or something - like over VNC?

if it dosnt work when you have the native machine running it from a more
local (more local meaning not over SSH, but with some means of actually
controlling the machine)

If at all else, run it on a clone machine with a real kb and mouse.

PS: are you SURE you want to use "cmd" and not the native VBScript system?
