sending instant messages

Hi mehnjalo,

Through the lan, you can use:

Net send <ip-address> <your message>

Greetings,

LucF

But your best bet will be some instant message client like Yahoo instant messenger/MSN Messenger/whatever, especially if you want to communicate over the internet.

Using the Net Send Command

Network message can be sent in two ways:

1. manual sending messages - from program window;

2. automatic sending messages - from scheduler, MS-DOS (.bat) or NT (.cmd) command file.

Manual sending messages
Standard solution of this task depends on user's OS:

In Windows 95 / 98 there is sending messages utility WinPopup. But as far as it uses API Win16 (obsolete but compatible with Windows 3.1x), there is imperfection:
you have WinPopup window with Windows 3.11 interface;
you have to remember exact recipient name or his PCs name;
you can't remove window button from task bar in Status Area (as known as Tray);
In Windows NT / 2000 / XP there is the only command 'net send' in Command Prompt or 'Run' window (hot keys Win + R). There is no program with Graphic Users Interface in Windows NT / 2000 / XP standard package. Main imperfections of this utility are:
you need to have Command Prompt window constantly open;
you have to remember exact recipient name or his PCs name;
you have too short edit box of a command line in 'Run' window;
it's hard to use Copy (Ctrl + C) & Paste (Ctrl+ V) command in Command Prompt window.

Syntax
net send {Name | * | /domain[:Name] | /users} message

Parameters
Name
Specifies the user name, computer name, or messaging name to which you want to send the message. If the information that you supply contains spaces, use quotation marks around the text (for example, "Computer Name"). Long user names might cause problems when they are used as NetBIOS names. NetBIOS names are limited to 16 characters, and the sixteenth character is reserved.
*
Sends the message to all the names in your domain or workgroup.
/domain:Name
Sends the message to all the names in the computer's domain. You can specify Name to send the message to all the names in the specified domain or workgroup.
/users
Sends the message to all users connected to the server.
message
Required. Specifies the text of the message.
net help Command
Displays help for the specified net command.
Remarks
You can send a message only to a name that is active on the network. If you send the message to a user name, that user must be logged on and running the Messenger service to receive the message.
You can broadcast a message to all of the names in your computer's domain (use * or /domain) or to a different domain (/domain:DomainName). Broadcast messages can contain up to 128 characters. Use discretion when you send messages to multiple users.
Examples
To send the message "Meeting changed to 3 P.M. Same place." to the user robertf, type:

net send robertf Meeting changed to 3 P.M. Same place.

To send a message to all users connected to the server, type:

net send /users This server will shut down in 5 minutes.

To send a message that includes a slash mark (/), type:

net send robertf "Format your disk with FORMAT /4"

No IP Option as far as Im aware :-(

please i need to use the ip through the internet

In that case I second Luc YIM or MSMessenger

You may already have Netmeeting installed on your computer (based on the assumption you are using Windows for an Operating System).
 Win XP will have it under Start-All Programs-Accessories-Communications, either way check your entire start bar before deciding that you need to install it.
Install Page:
 http://www.microsoft.com/windows/netmeeting/download/
  follow instructions.

How to use the program:
 http://support.microsoft.com/default.aspx?scid=%2fsupport%2fnetmeeting%2fhowto%2fdefault.asp

 One thing to keep in mind, once installed and configured, the IP's you use need to be routable.  In other words, if your friend has DSL, the IP they gave you may not work.
 Also, whatever program you use, your friend will also need it running.

net send ipaddress "message"  and that is all u need to do on lan.

thank you all but still something:
how to send a message to friend through the internet not allowing him to know this message from me as making jokes or as adversment

I know this is an innocent request, but getting onto another PC remotely without its owners consent is a crime in many countries. your only hope is to KNOW his/her IP address and net send a message to him/her, and hope they have not disabled this at their end
