Hey all I am trying to send a msg to user on my homegroup with windows 7 msg.exe command I have 4 laptops all wireless all on the same homegroup. I am trying to send a msg like "dinners ready" or "pick up the phone." to a user. The command: msg /server:Jay-PC Jay "I like Pizza" The Result: Error 5 getting session names I have verified the command it works to send a msg on my machine to my machine and i have verified the users. I have googled it and the only answer i can find is to edit my registry as shown below. HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server Name : AllowRemoteRPC Type : REG_DWORD Value : 1 And still i get the same error. Anyone know how to fix this error? Any help would be grand.
