How can I start an application on a different system remotely?

I've got a situation where i have one system running a master application that communicates with slave applets on other systems, problem is, i can't guarentee that the slave applets will be running, nor that an operator can physically utilize the system to start the applet (and I'm also assuming they don't know how to use Remote desktop, these are minimum wage test operators)

Is there an easy way to remotely launch an executeable on another system?

security is not a concern here as this is a closed network.

How can I control someone else's computer from mine?

On your computer, open Chrome. In the address bar at the top, enter remotedesktop.google.com/access , and press Enter. Click Access to select which computer you want. Enter the PIN required to access another computer.

If you're on the same network and have access credentials (username+password) to the remote computer, then Mark Russinovich's PsExec is just the tool you need.
