I'm struggling with getting media device discovery on Windows 7 working across my network. I have enabled multicast routing & PIM dense mode on the respective interfaces where the workstations are located, igmp snooping is enabled, the group 220.127.116.11 exists on all switches, and I can see that everything is working when I run "show ip mroute" on the switch. So the clients have joined the session, the route exists, but when i look at the network neighborhood on the workstations, I see nothing, except whatever is on the same vlan (local workgroup).
Am I missing something? Or does this just not work?
Oh, and I do not have a server with a domain, just workstations.
