Launch a process in a remote machine

I would like to launch a process in a remote machine, but I don´t know how I can do it. I am working with Windows NT.I know how I can kill a process in a remote machine with rkill, but i don´t know how i can launch it.
Thanks very much.

there is a REXEC command that is supposed to allow you to start a process on another machine.

If the application you want to launch is developed on your own
you can implemment COM interface. DCOM technology enables both launching and
killing such process either on local or remote machine quite easily.
It also enables to communicate with such process across network.
