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.
