Net send

Sends messages to other users, computers, or messaging names on the
network. The Messenger service must be running to receive
messages.

net send {name | * | /domain[:name] | /users} message 

Parameters 

name

Specifies the user name, computer name, or messaging name to send
the message to. If the name is a computer name that contains blank
characters, enclose the alias in quotation marks (" "). Long user
names may lead to problems when used as NetBIOS names. NetBIOS
names are limited to 16 characters, and Windows 2000 reserves the
16th character.

*

Sends the message to all the names in your domain or workgroup. 

/domain[:name]

Sends the message to all the names in the computer's domain. If name
is specified, the message is sent to all the names in the specified
domain or workgroup. 

/users

Sends the message to all users connected to the server. 

message

Specifies text to be sent as a message.
