Windows does this funny thing where it sometimes uninstalls the network stack when it doesn’t detect a ‘net connection… wasn’t what was going on here, but maybe that can help you? If you’re multicasting on a local machine (TTL 0) and it’s not working that might be the cause?

The only thing I have left is that it’s a hardware problem or OS setup problem.
