Re: Merging group issue

  Tim,

In addition to the same group name, the GMS clients would also have to
be using the
same multicast group address and multicast port.
Lastly, Machine A and B would have to be on the same subnet and UDP
multicast
needs to be enabled for the network and possible switches/routers.

They would find each other over UDP multicast and form a group when
network connectivity returns.
