as for the port 139, it has nothing to do with messaging, this port is a netbios session port for all file and print sharing.

Yes, If port 139 is not filtered and the message service is running you can net send them(Net send is a netbios function). This is how messenger spammers work. Also, to disable the messenger service via group policy means there is a domain which has its own securtiy policies which are used when logged onto the domain and set by the domain controller. Also using NetBios in conjuction with RPC it is possible to execute commands remotely and basically do whatever you want if you have the proper permissions.

lol, i remembered this post from a while ago and though i would post my incident that occured today.

I wasmessgina around trying to get the computer next to me to shut down through command prompt. i typed in "shutdown -m <IP> -s -t 1" and noticed that it didn't work. I wanted to see if net was enabeled so i tried "net send <IP> TEST" and it did nothing. Then.... thinking that NET SEND was disabeled i typed "NET SEND /DOMAIN TEST" and pressed ENTER.

The ding of a message was heard throught the room as every computer in my school received that message. I had also failed to realize that if you do not have a name specified its uses you computer name as the sender. My computer happened to be named <Room#>_HS_<ComputerNumber>. The next thing that happened was my computer teacher can running in the room from upstairs and stopped as soon as he saw me. "<MY NAME>" he said. "I had a feeling it was you".

I found it kinda funny. Also kinda sucked.

So did you get into trouble.
I never heard a word about it the next time I went to class.
You would think they wouldn't care, it's really not that big of deal. If it is wrong for you to do it then it should be disabled. Anyways, I feel your pain and satisfaction.
