How to send instant messages over secure networks

Well here is a way to send instant messages to your friends over such networks as long as you have their ip or the name of the computer on the network.  An easy way to find a computer's ip address is to type cmd in the run box on your start menu.  This will start the command prompt.  Type "ipconfig /all" with a space between "ipconfig and /all".  That will list the computer's ip address along with other network specs.  Now that you have the ip of that computer, you may send instant messages to it.

Go to the run command in your start menu.  Type cmd in the box which will open the command prompt just like above.  Type:  net send "ip address" message.  If the computer you were trying to send a "Hello" message to had the ip address of 127.10.1.1, you would type "net send 127.10.1.1 Hello" 

Additionally, it is possible to use a wild card such as * in the ip address parameter.

Example: net send * message

The above command will send your message to every computer on your subnet.  This is great for system administrators to send out messages to all windows computers on the network notifying them that you are going to be taking down the server or something.  However, if you are a student and feel like pulling a prank at school by sending some message across the school network, you will screw yourself.  With today’s zero tolerance policies in schools, you will be suspended possibly even expelled.  Trust me; it’s happening all over the USA.

    I guess this trick would be good for a beginner, but about the "dont do this at school" thing, too late, did it, didnt get anything done to me, closed subject. Schools should be happy that their students are smart enough to send these "Instant Messages" you call them...

    #17 the only way to get it back up and running is to enable the actual service and you would need admin privilages its not unistalled its just that he probably stopped the service from running and executing automatically =) hoped i helped (btw i go to a school and me and my friend are trying sumthing a little different to this he he) ill update you all when we get sumwhere :p

    I had the use of this from a cisco class and to use it you can use a computers network name as well. Hold the windows key down and press r. This will bring up the run command. In my school the computers were all numbered so I would just type: net send 121b01 Hello and the message hello would appear on the computer. Taking it further look on the web for windows Spoofer. It has the option to change how the message shows up on the other computer. For example we had message sent by God to Jim at 11:43:06 Hello. The feature however can be disabled and only re-enabled by an administrator password

    This is a common trick, but it doesn't work much anymore because the "Messenger" service which it depends on is often disabled by default. The service can be started, but most places like schools will have it disabled.

    if you cant get command prompt at school, try the following open notepad and type "command.com" (without the quotations and save it as a .bat file to somewhere you can find it (your personal network folder or something). Open the .bat file you saved and command prompt should pop up. Good Luck :)

    Great, if I could remove sp2 from all computers. Here's something for those who want to show of infront of their friends. THIS WILL GET YOU IN TROUBLE (if you have really stupid admins and a retard who dobs on you), I got suspended for it. This is the best thing I did at school. REMOTE SHUTDOWN COMMAND shutdown -s -m \computer_name replace "computer_name" with the name of the computer you want to shutdown

    I'm not sure if this was mentioned above, but, all XP comptuers with SP2 automaticly have it disabled due to hackers using them back in the day on 2000ect. Well, to enable it on XP goto Start menu, then run. In run type Services.msc scroll down the list until you see Messenger. Right click, click properties and set it to automatic. Then click apply, then go back in and click start. This will start it up completly. Then go to CMD and do what you normaly did. **WARNING** be careful using the NEt Send * function, some people did it whenI was at UNI, well uni was using a government WAN and it crashed their server because ofr the amount of messages. They were expelled and had to speak to the police for willfull damage. But yeah, hope this helps people.

    This is a great feature, and as some of us have found out, great for school, my girlfriend's math class a few years ago was bugging this new teacher we had, ever since then, though, they've disabled it, were still looking for ways around it, but if your on a seperate network from the school's, like in a networking class, great prank to do when playing a full screen game (it minimizes the window, so if you plan an attack, like in Star Craft, and you want a head up, make a batch file that keeps sending random ppl messages, wont be able to fight back)

    if you cant get cmd at school just open notepad and type COMMAND then save the file with the name "cmd" or a secret name, what you want, and the extension ".bat". then you run it, after you have done that, cmd will open at most schools.
