Just a thought -  the DHCP server may have decided to give its only real
IP address to the first client which requested one, and thereafter give
out private addresses. Was the Windows machine the first to connect? Is
it possible to remove the NIC from the Windows machine and put it in the
BSD machine to see if it then gets the correct address? Or can you set
an explicit MAC address in NetBSD (In Linux you can if the card supports
it; in OpenBSD it seems you cannot; I cannot be bothered to boot NetBSD
to check)? If you can you could try setting NetBSD's NIC to the real MAC
address of the Windows machine which works (with the Windows machine
disconnected of course).
