If the workstations are running on NT work station you can use Net Send.
This does exactly what you are
looking for. This is how you do it from VB.

Syntax:
Shell "Net Send ComputerName Message"

Example:
Shell "Net Send PC5 Hello"

Use Shell to launch the program Net Send
PC5 = the computer name of which you want to send the message to. you can
find this in control panel, network

DCOM would be one way to do it.

Two alternatives ... One is to use the NetMessageBufferSend API (the target
can be a NT system where a MsgBox will appear, or a Win9x system running
WinPopup). The second is to write you own using the Winsock control. I have
samples of both at :
