Can i have a straight answer on how to use msg command

[Sico Music]

Ive spent a few weeks going back and forward to this command. For those who dont know msg is the new net send.

I cant get it working at all. Not at home or at school.

For school I use the following command:

msg /serverETNSW.WIN SA4335675

Then it comes up with Enter message to send; end message by press ctrl-z on a new line, then ENTER.

Now I just realized that doesn't work at all because I tried it at home and it still comes up with that.

For Home I tried:

msg /server:WORKGROUP Study2-PC

Same thing happens. I think that just sets up a server or something instead of connecting to it. So how do I connect to the network and send messages though it on windows 7. I have been able to send messages to myself with following command:

msg * "hello"

But no one else on the network gets it. I'm confused please help, I have asked on other forums and gotten no help.
