Net Send Lite is a small utility that uses the existing Microsoft Messaging Service to send network messages. With Net Send Lite you can send messages to a specific username, computername or domain/workgroup on your network. Simply click on Add/Edit Users to create a usernames.txt file, then select the name from the list and click send. It's as simple as that! Net Send Lite includes many options, such as the option to include a footer on every message, save the last user sent to, clear the message after sending, or set the ENTER key to send the message by default.
One of the downfalls of using Microsoft's "net send" is that when a user receives a message it says it was FROM the computername. As you know, the computername is not always informative to users. Net Send Lite allows you to resolve the sender's login username, use the computername or specify any name you want as the FROM in the message. There is no client installation required for users to receive messages.
