Messenger Service and Net Send
This page talks about the Messenger Service, which is built in to all versions and variants of Windows NT, which includes NT 4.0, Windows 2000 and Windows XP. It is not included in the Windows 9x line (95, 98 and ME). It should also not be confused with the Windows Messenger or MSN Messenger application which is a separate product.
What is It Used For?
The service is primarily designed for use on a network. It allows network administrators or applications to send messages to users or machines. These are one way messages, that appear in the form of a pop up message similar to the one below. You cannot reply to them directly - you would have to send a new message.
Example uses would be a network wide announcement (Server going down), an application sending an alert to a certain group of users or a message sent from one individual to another.
How Do I Use It?
If you want to use the service yourself, you need to know either of the following:
Unless you use extra switches in the command line tool, to use those marked domain or workgroup only, you must be in the same domain or workgroup. The message will not look on other domains or workgroups for a username to match. However they will cross IP networks. For example if you are in the same domain but a different site, you should get the message.
Using built in tools, there are two ways to send a message to another computer and just one for sending to an individual.
Command Line Tool
You can send to any of the targets from the command line.
Computer Management Console Tool
You can also send a message to another computer ONLY via Computer Management Console.
Third Party Tools
There are also third party tools which you can download which provide a nice interface for this command instead of the command line.
Alternatively check your favourite download site to find others.
Not Receiving the Messages
If you are not receiving the messages, you should check the following:
