The broadcast address *should* be 192.168.0.255, not 192.168.0.0.
It's a known misfeature that SunOS <= 4 uses 0 instead of 255, but I
didn't know that FreeBSD would do it. When I try it (all FreeBSD
boxes :-), I don't get any reply from 0.
I'd guess that the answer to your question is one of:
1. You have misconfigured the Microsoft box.
2. The Microsoft stack is broken. We know this to be the case, but I
don't know if it's the correct answer in this case.
I certainly wouldn't worry about it. Sending pings to a broadcast
address is Bad anyway, so maybe the Microsoft behaviour is preferable.
