NET SEND

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:

Windows 2000

1. Click Start -> Programs -> Administrative Tools -> Services
2. Scroll down and highlight “Messenger”
3. Right-click the highlighted line and choose Properties.
4. Click the STOP button.
5. Select Disable or Manual in the Startup Type scroll bar
6. Click OK
