trough the cmd, when I use the ping command to reach 192.168.11.111 it works perfectly. but when I use the msg.exe it can't find it. this is the command I use: msg 192.168.11.111 "test" Am I missing something? EDIT: Just to make the question more clear: I want to send a message to ip 192.168.11.111 The problem is, it says the host is not in the network while I can ping to it just perfectly
