Net
Send command is used to send messages to other users, computers, or
messaging names on the network. The Messenger service must be running
to receive messages; it is automatically enabled when you install
windows. You can send a message only to a name that is active on the
network.
Messenger Services can be used to send advertisements
and spam to vulnerable machines on a network. A box will pop up on your
screen with the text “Messenger Services” at the top, but the text will
be an ad for a product or service interrupting whatever you’re doing on
the computer at the time.
To make sure this doesn’t happen to you, just take the following steps:
