It should be interesting to know what exactly version of Windows runs
at faulty client? And was any of IPv6 services activated on it
(including Teredo)?

Your tcpdump (or whatever on Windows, Wireshark?) should show ICMP
Unreachable packets before that error. At least many people get this
when they receive 10054 error on UDP sockets.

So probably more workarounds for Windows. One of them is probably
ignoring 10054 return value of recvfrom on Windows.
