In every LAN where various PCs are connected together, sharing resources and information, there is one essential element you must have: a little program to send messages from one machine to another.
And this is exactly what NetSender does, a simple, very basic and austere program that lets you, in a simple way, send messages among users of distinct PCs. You just simply have to write the message and then select the PC you want to send it to.
This way with NetSender all the PCs on a LAN can communicate and inform each other continually.
This version only works with Windows NT and 2000, for Windows XP you must download
NetSender XP.
