Network Application - basic question

How do I communicate between different user instances of my windows
forms project?

Im trying to write a program that will run on a network of 15 pcs.

5 of the pc's will run the admin part of the program. and the rest of
the pc's will run the salesman part of the program.

Both forms (the admin form, and the salesman form) at this stage are
VERY simple as i'm just trying to learn the mechanics between basic
form communication accross the network.

The admin form has a couple of labels, a text box and a drop down box.
The text box allows the admin person to enter a leads name, and the
dropdown box allows the admin person to select which salesman they want
to send the lead to. Then when they press OK here is what i need to
happen...

Lets say from the dropdown box they selected the salesman called JOHN.

On Johns PC the app will popup a box alerting him that he has an
incoming lead.

It then pops up the salesman form, with the previously entered customer
name already populated and the time and date info also populated from
the data the admin person entered before they sent him the lead.

Can someone please explain how I achieve the above. I can create the
forms with no problems of course, but my question is asking about the
network side of things and how i actually get the forms to communicate
with each other / and find the right users form to activate.

Many Thanks.
