Hi! The simplest way I see you can accomplish this is by using the NET SEND command. Follow these steps to get it running: 1. Right-click My Computer and select Manager 2. Go to Services and Applications - Services 3. Right-click on Messenger and select Start, if it isn't already running (you might have to go into the Properties and set the Startup Type to something other than Disabled - set it to Automatic) 4. Go to Command Prompt: Start - Run - Type "cmd" and press Enter 5. Type "hostname" and press Enter. This displays your computer name so write this down or remember it. 6. Go to the other computer and repeat steps 1-4 7. Type "net send " followed by the name from step 5 and then your message Eg. "net send nitinrk hello there" If you prefer to use a graphical interface, you could use NetMeeting. It's usually installed with Windows, but as there aren't any shortcuts, you'll have to look for it in C:\Program Files\NetMeeting and double-click conf.exe (the one with the icon of a globe with 2 converging orange arrows). After startign NetMeeting on both computers, you can find the name to type to call the other computer using Step 5 from above. Feel free to buzz me back if you need more help. Regards, Nitin
