|Thanks very much for the answers so far.|
I am not trying to login remotely, just want to start the job running before I get there, which will mean I can get on with other things earlier as well.
Wanderer, if I read it right, your second paragraph sounds exactly like what I want to do if 'the script' can launch the remote batch file. How can it be done?
Ace_omega, AutoHotKey looks interesting, I will give that a try and feedback.
