using the following command

msg /server:pcname username message

server stays as is. pcname is the name of the pc you are sending to. user name is the name the user is logged in under on that PC. message is obviously the msg u want to send.

you will also need to change a setting on the receiving computer by using regedit.

the following registry key must be activated (as described by Consoles above):

HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server

Name : AllowRemoteRPC

Type : REG_DWORD

Value : 1 (the dafault is ‘0’)

(not tested myself: need to verify)
