Send LAN messages

I would like to send message to targeted receivers.

I need to warn my users with LAN messages in case of breakdown of applications, and not mails because nobody read them!

The below command will do what you want on a windows network, provided you have permissions and the admins have not blocked such messages.

NET SEND

{name | * | /DOMAIN[:name] | /USERS} message

Further information can be found here.

You can't find net send under Windows 7 because it disappeared. but you can use software as desk alerts with dmessage to send lan message.

Was looking around and found this program: Winsentmessenger

It takes a bit of work to get setup, but it should work on all versions of windows. That being said, I would still recommend that you use OS provided services like "net send" or "msg" depending on your OS.
