Techopedia Explains Net Send

Net Send messages may only be sent to active network names. When a message is sent to a user, the user must be logged in and running Messenger Service to receive the message.

A message may be broadcast to all names in a sender’s computer domain but may only contain up to 128 characters. The syntax is “net send {name or * or /domain[:name] or /users} message.
Microsoft advises discretion when sending messages to multiple users.

Messenger Service was originally designed to allow system administrators to notify users about their networks. However, it has been used maliciously to send pop-up Internet ads through mass messaging systems. The Windows XP firewall was rarely able to prevent these malicious attacks. Windows Service Pack )SP) 2 disabled Messenger Service and enables firewall by default.
