MSG is a program for sending NetBIOS, or more commonly known as "Net Send" messages from a graphical interface. In addition to being a lot easier to use than the command-line based "Net Send" in Windows, MSG allows you to do a lot of things that "Net Send" can't. Features include the ability to search your workgroup or domain for available computers, the ability to send to entire workgroups or domains, the ability the specify the "From" field of the message, and the ability to easily browse file and printer shares on local computers, all from within an easy to use interface. MSG is a very useful tool for dispensing messages quickly on your LAN.

If you install the optional MSGProxyService component on a web server running IIS, you can also send to computers on the workgroup / domain local to the web server from a remote location. So, for instance, you can install the MSGProxyService on a web server on your company network and then have all of the same capabilities from the MSG client that you would have if you were on your local LAN. Sécurité features of the MSG client communication to the MSGProxyService include password protection, message integrity verification, and replay attack prevention.

MSG is made available as FREEWARE. It contains no viruses, adware, spyware, back doors, or trojans.
