All computers on your network should have the same 'Group Name' - as far as MS is concerned. The real thing is that it would help if they were in the same IP range, but you will need to check that before attempting pinging them.

Another clever thing is that computers on a network will happily work (after a fashion) with duplicated IP numbers - been there, done that, got the T-shirt!! ;-) but the NETWORK objects strongly to that...
