I don't have a link for this, but I know well that, on a Windows machine with more than one NIC (network adapter), outgoing broadcast messages have the FIRST network adapter's address as the return address on messages going out all NICs. The receiver on the second network uses that (wrong) address for the response, and the response doesn't get back to the PC. Disabling and enabling may switch which NIC is considered first (not sure about that).
I've seen this on Windows XP but haven't tried to repeat it on Windows 7. The problem is in the OS.
Thanks for the answer but I'm not sure to understand exactly. In my case the sender has just one NIC. The problem seems on the client in which there's one or more NIC created by VMWare. The client, in my case, just listens to udp datagrams and never needs to send anything. Regards Gianni
