Raising methods in another executable

I want to create a sort of dispatcher in VB6.  This program should run on the server, and should be able to raise events on several clients.
Server and clients are connected through an Ethernet TCP/IP Windows NT network.
Any idea how I can raise an event from one program  executable), and capture that event in other executables (ActiveX or standard)

Any suggestions more than welcome.

First you have to use a timer to check continually for an event.
Second, a program have to generate an event.
 Here are possible solutions :
   - Checking for files. I used that solution at work because
     some process are running under Unix, and other under NT
   - Sending message through pipes
   - Use the Winsock to communicate
   - Use DCom (I have sample, but never used this for the moment)

Make a choice. The easiest is using files. Here we use 2 files, 1 file containing the data, and one flag file. The process check for flag files, when they appears, they read the data file, then delete the files.

I'm very interested in your DCOM sample.  I do not want to use files, simply to avoid that my client would have to be polling all the time just to check if the file or its content are there (this generates network traffic, and that's exactly what I'm trying to avoid).  Can you send me the sample ?
