There are lots of ways to accomplish this... One common method would be
to use a socket. Look at System.Net and System.Net.Sockets. A good
place to start with .NET sockets:

Another method would be remoting. It's also possilbe to use the
Microsoft message queue or even using named pipes. Like I said, there
are many ways to accomplish what your trying to do. You just need to
figure out what is the best method for your particular application.

You can do this using Windows sockets.

Look around on Google for one of the various (there are several) VB.NET
examples using TCP to chat across a network. The same thing can be done to
send messages. This should be good if you are doing simple point to point
communications, even if it is one server sending a command to a single
endpoint or a single endpoint in a pool of possible endpoints.

If you want to send out a broadcast type message from one point to several
endpoints at the same time take a look into UDP Multicasting. I can't seem
to locate any good samples of this right now but I know I have seen some out
there.
