I use it over RDP; the trick is to put your mining script in the startup folder, and then disable the password requirement for logging in (start->run->'control userpasswords2')
then to kick off mining, just reboot the machine from RDP (ctrl+f4 from desktop)
kind of a pain but it works.
That's one way to go about it, if you can do it that way then a scheduled task should work just as well. I was hoping someone knew of an application that would let you run the command line as if you were at the console. Trying to avoid running a VNC server. Logmein\ any web based remote access apps kind of scare me, especially whith all the BTC robberies going on recently. I'll do some research and let you guys know what I find out.
