or workgroup

specified domain

Is the actual message sent (no quotes required)

Examples

Send the message "Save your workrebooting in
5 minutes" to all users who have open sessions with
the server:

net send /users Save your work--rebooting in 5 minutes

Notes

• In order for a user to receive messages, the Messenger service must
  be running.

• Use quotation marks for computer names or usernames that have
  embedded spaces in them.

• Messages can be up to 128 characters in length.

• The message queue, which temporarily stores messages for the
  Messenger service, can store a maximum of only six messages; any
  further messages are ignored if the previous ones
  aren't acknowledged.

• net send *
  is the same as net send
  /domain.

• Broadcast messages (* and
  /domain options) are sent over all network
  protocols. For example, if you have both TCP/IP and NWLink installed,
  messages will appear twice on receiving machines. Messages sent to
  specific recipients are received only once, however.

• Broadcast messages are received only on the local subnet unless
  routers are specifically configured to forward NetBIOS Name Query
  packets.

• Messages sent using the /user option are sent to
  each session established with the server. If a user has three
  sessions open with the server, the message will be received three
  times.
