Communication between remote scripts

[ChrisH]

I have a python script (A) that monitors a process (3rd party) on the 
local machine (Windows).

I would like to create a second program on a remote Windows computer 
that receives an update from program A periodically (maybe every 10 
minutes or so), and tells it everything is running without a problem.

Can anyone recommend a good (and preferably simple) way for two programs 
to communicate on a network?
