I have a NTWS running on the LAN handling the entry of "job requests". These are put into an SQL DB by the WS. I want to have a small tray process running on several users PCs so that when a certain type of job request is received by the NTWS a notification will popup in the tray(s) of certain users PCs. I know you can use WinEvent to create and handle tray processes and can set it to start when the PC boots but what NetTalk functional should I use to "send" the notification from the NTWS to multiple PCs? It's sort of like the NT Chat example but I know that's probably not the way to go. Are there any NT examples that I should be looking at? Thanks
