I mean the network adapter created by a virtualization tool (like VMware).
I verified that a client on win7 with a such network adapter active does 
not work (I'm talking about udp multicast, while TCP works perfectly). 
On the other side if I disable the "real" card and then enable it again, 
udp starts magically working.

Any idea?
