What's the easiest method of distributing a program over a network?

I've got a program that we need to run multiple instances of, we have loads of computers that could all run an instance of the program. But it would be fantastic to automate this distribution somehow.

So what's the easiest way of accomplishing this? The computers are windows and all networked together. I'll consider any programming language.

Sorry your right, a little more info would help.
Basically I've got thousands of PST's that I want to run scanpst over.

I've written a small batch script that allows using scanpst via command line and I'd like to distribute the files over the network onto each computer, run scanpst over a batch on each computer and then return the files back to the original computer.

I'm considering using Java RMI but I was wondering if there was a simpler alternative.
