Hi vbeans, happy MakaraSankranti....

I want to create a program which should run only at my system and when i enter a message in a textbox and click SEND button then the message will display all the other computers in the LAN. I can not install any program in any other computers. I know all the IPs of other coumputers. Is it possible in vb 2005? I tried to make a program with NET SEND but failed because some computers are XP based and some are VISTA based and some are win 2000 based. Message is not displaying. Please help....Thanks in advance... Sunil Nair
