MSG Command on CMD result Error 5 getting session names

I have 2 computer connected over LAN. Both has windows 10 pro version 1607. I open cmd from 1 computer and try to use message command like this :

msg * /server:lenovo-pc "Hello"

Lenovo-pc is other computer name. The command result Error 5 getting session names

How to fix this problem ?

• I already set the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\AllowRemoteRPC from 0 to 1 and already restart.
• I already run cmd with level admin.
• Network discovery, file and printer sharing on private and public network already TURN ON on both computer.
