You can use the WinPopup tool (
WINPOPUP.EXE ) in Windows to send messages to users, machines, or entire workgroups on the network. This tool is provided with Windows 95 OSR2 and comes standard with Windows 98. With either Windows 95 or 98, however, you need to be running WinPopup to receive and send WinPopup messages. With Windows NT, you can still receive messages without starting such a tool; they will automatically appear in a small dialog box on the screen when received. The WinPopup application is shown in
Figure 8.1.
