I also want some more codes for cmd i only know a few off of youtube.

• Answer:

  it will not be possible to send this message via "net send" outside of your network. Also you are trying to use this command through the internet which is definitely not possible. Also there is a service that has to be enabled on a computer in order to receive "net send" messages and I believe that it is disabled by default in Windows XP now. I do not recall the name of the Service.
