Okay, so I have done research on attempting to learn how to send messages accross my LAN, of course with out having to download a typical instant messenger. Sure, this would be the quickest solution but, the way I see it...I won't have to sign up for anything...

Maybe I would just like to surprise the other computer user with a message, mostly I just want to know how to do it just because. If I could get some assistance on this that would be awesome!

Below is a command line I saw to try by googling the theory, this is my result..

from the command prompt..
QUOTE

C:\>net send Brian2/255.255.255.255 test message
The syntax of this command is:


NET SEND
{name | * | /DOMAIN[:name] | /USERS} message



C:\>NET SEND {Brian2 | * | /DOMAIN[:name] | /USER
S} test
'*' is not recognized as an internal or external command,
operable program or batch file.


the domain name is bolded because it is apparantly not a true domain name...regardless, you get the idea...I like a wee bit of privacy

The instant messengers all use their own dedicated port. If you download an open source version (Pidgin is a great example) You can see how they work.

However, the windows messaging servers that you have mentioned is able to be turned off. I'm actually missing the question of your post.

I want to actually send a message from one computer on my LAN to another, the method which I used is in the quote along with the error message and such....I did a google search and that method is the ONLY method I could find. Every other website was a dead-end.

Apparantly I'm going to have to have a program eh? I was just thinking I could get a message to pop up on one of my other computers kinda like what you see in movies (ie Hackers) but thats not what I'm aiming for....

The deal is I have quite a few cpu's in the house, I want to be able to pop up a message to someone regardless of them having an instant messenger...know what I mean?

Also, I have used a program once before where I could control my computer from any other computer...other than windows assistant, is there any other way of doing this w/out downloading another program?

In order for a machine to receive & display such a message, it's going to have to be listening on a port, as well as know how to manage such information coming in. Even the windows messenger is a service, dedicated to a port, listening for traffic.

Again, these programs need to work on both ends. Something can't just automagically grab control of the mouse over tcp/ip when your mouse even is listening on the USB or PS2 controller.

Have you looked into using Remote Desktop? I believe that this might be one of the few items that only work with XP Pro (If we are in fact talking about XP here).

you will need to enable the windows messanger service to display net send commands although if it is enabled you will get spam messages popping up from some douchbag advertizers.

the command will go netsend computername message

and look like this

c:\> NETSEND comp1 You are a fuggin moron

and they will get a popup saying

You are a fuggin moron

You won't get any spam if you have a router. icon_up.gif

I've run unpatched Windows 2k/XP boxes for years behind a router (with net messaging on). Never got a single spam winpopup.

When I used to run Win 2k I think I got one, like ever.

If you have office 2007 enterprise which you can usually buy for about $75 US with any type of student/school ID, you will have your own IM for your network since a private IM is now included with the top versions of office 2007. This appears to be a great feature of office 2007 that most people are not aware of yet.

I don't mean to attack your post, but why would anyone want pay for an office suite to get an instant messenger? blink.gif
