It tells me that the mDNS info is coming out of the windows box
(multicast), but that all the requests for detailed information are
not.. (either not being received or not being responded to)
Since you've checked that the firewall is not blocking mDNS traffic,
something else must be...
1) First option: winswitch + mDNS is broken on windows. That's unlikely,
but I could have missed it, I will check at the earliest opportunity.
2) More likely, something is preventing bonjour from operating properly
on windows. So I would use normal network diagnostic tools (telnet,
tcpdump, etc) to figure out where things get stuck, comparing it with
the traffic from a working setup.
Assuming that the problem is indeed from mdns, you may be able to get
more help on a list dedicated to it.
A potential workaround, which I have not used in a long time, is the
"reverse multicast" option of winswitch. This would have to be enabled
on *all* the clients, and would require an extra port to be punched
through their firewalls.. not ideal.
