Step 1: Opening Command Prompt

this part is pretty easy, anyone who has used command prompt before knows how to do this, all you need to do is hold down the windows logo key and r to open up run, or you can just go to start>run

once in run, type in cmd or cmd.exe and then press enter
the command prompt shell should now be open

Step 2: Enabling the Messenger Service

now you are going to have to enable the messenger service. do this by opening up run again, and now you type in services.msc and then press enter

a new window will open up, find the name "Messenger" (no quotes and in alphabetical order)
right click on messenger and select properties.
once in properties on the drop down menu select automatic and then click apply.
once apply is clicked, click on the Start button to start the service

Step 3: Using Net Send

Picture of Using Net Send
now that you have the messenger service activated, it's time to learn how to send messages

the format for net sending is something like this:

net send (user/IP address) message

an example is:

C:\Users\z2daj>net send z2daj Hey

you can only use users if you are on the same computer, if you want to send messages to other computers, you have to get their IP address AND activate the messenger service on their computer as well

to get the IP address all you need to do is open up CMD and type in ipconfig (one word) and then press enter, the computer's IP will be under IP Address...

Step 4: Sending Messages

yes now for the moment you've been waiting for, the actual sending of messages

open up cmd
type in net send (IP) message
i recommend that you use the system's IP for two reasons
1) IP's are unique to computers
2) Using Users does not always work

i have my ip address whited out because i don't want anyone to know my ip

if you have different Windows systems better to use lan messaging solutions like Softros, lanmsngr, usually these apps works well in XP, 7,8 etc without any additional services.

yeah if u could try it on vista that would be cool this is what happens for me i cant get it to work
Apparently, NET SEND was disabled on Vista. But I'm working on a fix. Should it work when I try it, all you will need is an XP computer and a means of file transfer... also, I'll make it into an instructable.

hey... I cant get this to work, and I don't feel like trying to fix it so i'm asking: What happens when you specify the computer loopback address? (127.0.0.1)
 When you specify the loopback address youre sending your message to yourself

ok i did it fine on xp and my friend is trying it on xp but he cant click apply. it says he cant apply to local computers. i tried to help him but he cant click yes or start or apply . what does he do? ps it works but i cant send stuff to people unless they enable it too?
z2daj (author)  manndude14 years ago
yeah, late late late late response! anyway, it only works if both computers in question have the messeneger service enabled, and as for your friend, is he the system admin?

z2daj (author)  johndoe117874 years ago
 yeah, unfortunately the last OS that Microsoft added this to was on Windows XP, it can't be done in Windows 7 or Windows Vista as M$ completely removed this service from Windows

This is exactly why the first thing I do when I set up a windows machine is disable the messenger service. I'm pretty sure ever since SP2, though, MS has this service disabled by default.
...yeah, if was an okay thing to do there would not be so much stuff marked out with white splotches.

i just don't want anyone to know my personal IP, at school, who cares?
your personal ip address is behind a router. noone can get to it unless they know your external ip

thnx alot, dude. this helped me out alot.

Yeah im so doing this at school =) Keep up the good work z2daj
Yep, since SP2 this has been completely disables unless the user goes into administrative tools and reenables it. The other interesting command is shutdown -i. The -i argument adds the user interface. This command will just down any computer name you give it. It usually works in large corporate areas where the administrators have enabled this so that they can massively shutdown every computer in response to a security or electrical issue.
Someone please help me! i did everything here and it says... Sending files is no longer supported. More help is available by typing NET HELPMSG 3777. ... what should i do? please help me!!
that means net sending isnt enabled on your network. it usally isnt because if it was its really easy to make a batch that sends everyone a nessage over and over again. really anoing
z2daj (author)  wrestler 1036 years ago
you probably didn't start the service, and if you have it on vista or your router is blocking the message port that could be the problem, post back with EVERYTHING you did and i'll see what i can do
thanks for trying to help... OK I have windows xp home on my main computer (the one I am using now) and my second computer which runs xp professional. I have a network that runs off of a Linksys© switch. I turned on messageing on both computers and it still has the same message. Does anyone also know how to share Internet connection over a switch? I can't seem to get it to work.
z2daj (author)  wrestler 1036 years ago
are you using the IP address as the user? try that, and by the way, are the computers hard-wired or wireless? and are you sharing the internet connection over the switch?
they are hard wired with Ethernet cables, lol. Yes, I am trying to share over the switch but its not working for me. please help! how would I use the ip addresses, like how do I set it up in command?
OK I got that net send to work... it works just fine, but I still need help with the Internet sharing part! Also, check out my first Instructable! It is under my page.
z2daj (author)  wrestler 1036 years ago
im not sure if you can share an internet connection over a switch unless you get more than one IP address from your ISP, so i say go for a router
How would I get more than one ip address, what would it consist of, would I have to buy it? I heard that a router is better anyway. Say I got a router, what would I do to set up ICS? Thanks for all your help! Check out my first Instructable! Just click on wrestler 103 to view it.
z2daj (author)  wrestler 1036 years ago
yea just get a wireless router, i recommend the Linksys WRT54G router, then get some wireless cards, and then bingo you got a shared network/internet wirelessly
would i be able to get a wired router? it would be alot easier since i already have the cables and already have wired ethernet cards...
z2daj (author)  wrestler 1036 years ago
yea the WRT54G has 4 ports on the back where you can use it as a hub, i haven't used that, but i hear that it works great
if i get a wired router, i would just plug in my computers on the back... i have dial up internet, so how would i get that to share over the router?
