(as noted, it does depend where the farm is - if all machines in the farm are on the same network, e.g. set up in the office, then remoting in to one master machine and kicking things off from that can be done, with just regular Backburner or third party software or even Corona DR. However, if all the machines making up the farm are also in different locations and not on the same local network, that's where things get unknown from our side :) )
