Net Send: A primitive instant messaging service?

Nowadays, we use programs such as Yahoo Messenger, MSN Live Messenger, or even Digsby to chat with others online. But what you may not know is that before even these became popular, there was an older utility program that its sole function is to send instant messages anyone inside the network; the NET SEND command. It's major difference to other instant messaging (IM) programs, the NET SEND is purely a text line interface when sending messages, and it has a pop - up window in which messages using this utility are received here.

When using it, you must open your command line prompt or the cmd shell in your Windows OS. There are different variations on how you use this command:

1.) NET SEND {user name} message
     - This command syntax is normally used to send instant message to another computer within the network using its user name.
2.) NET SEND {computer name} message
     - This command syntax is normally used to send instant message to another computer within the network using its computer or PC name.
3.) NET SEND {*} message
     - This command syntax is normally known as a broadcast message to the domain wherein a network is connected.
4.) NET SEND {/USERS} message
    - This command syntax is normally used to send instant message to all users that has a session within the server.
5.) NET SEND {/DOMAIN} message
    - This command syntax is normally used to send instant message to another computer into another domain.

Although majority users do not use this utility as a form of instant messaging service, network geeks are certainly knowledgable with this utility. And maybe once in a while, I think you should try to use this utility. Because this one utility that may be helpful to you, in case you want to become a network administrator someday.
