Wow, it looks like you guys have most of it covered but with a few key things missing. The best and most informed article I've ever read on the subject is on a site that is shutdown now.

Also note: Companies that have sensitive information (such as the government or other big businesses) often hire hackers to try to break their codes and machinery, often using black hackers methods, but it's completely legal as permission is given to do so, so that they can fix any holes in their systems. It's a well paying honest job, in my opinion.

I did that today at school. Net Send isn't hacking at all. It's a useful way to message people quickly on local networks, so lets just say we're not trying to do this at school. But some schools tell their students to use this..

That will tell everyone "Hai!", and will tell them which computer it was from. They will be able to check who was logged in at the time that message was sent, so don't do that, or you'll get in shit, and possibly expelled from certain schools. (They just don't like anybody messing around with command prompt.)

Write the code below in notepad, and save it as Messenger.bat
When you're done that, open it, and enter an IP address from someone else in the same local network, and a message. It didn't work with me at school when I tried it, so I did "*" for the user, and it successfully sent "Hi." to everyone in the "WorkGroup". I haven't gotten into any shit yet, so I don't think it displayed it to anyone lol..

Goto control panel, click on administrative tools(switch to classic view) Then click on services. Find messenger service. Open it. You'll see startup type which would be disabled. So click on that and select manual. Now press the start button and apply. Do the same on the remote computer. Until this service is activated on that pc, you won't be able to use this.

Enter an IP address to send it to someone. To get the person's ip address, you do: in command prompt on [b]their[b] computer. And it's there.
Use that, for "user:" and then whatever you want for "Message".

net send is not a valid command...

On XP?

Yeah it is, I've used it before, and Matt, usually when they want you to use "net send * HAI!" it's because your lab is in a separate network from the rest of the district/school.

Okay. That was my first attempt at making a batch file. Fun.

Man, you guys' schools must be really insecure, I was only able to get access to command prompt through command.com, cmd.exe was always blocked, and to get to command.com I had to make a .bat file But since I broke Novell there are no limitations anymore

Be careful what you do, some schools are quite strict about this kind of stuff. One kid got suspended before just for having the command prompt window open.
I got in shit one day for using telnet.

Yeah, but since I'm in a computer programming class, Console windows are open all the time, and they look almost the same as the command prompt. And my teacher's cool too

Lol yeah then that's fine. But playing with telnet in english class... is what i did

OMG what a shitty teacher...

On Vista.

I always forget that all of you are probably running XP.

net send isn't supported for Vista for some stupid reason.

It was used for spam, apparently...

Yup, apparently, you're dead right.
