Long since I’ve posted any PC tips, so here we go. This post will introduce you to the net send and msg.exe and tell you how to use it to send messages to other PCs which are connected to your LAN. :)
The net send command works for most of the versions of Windows upto Windows XP SP 2. Due to the use of the command for spamming over the WWW, this command was replaced by msg.exe in Windows Vista and Windows 7.
