If machine A (if I got your topology right) is using WINS and the host on
the external subnet is in WINS, and you are pinging by it's single host name
(not the whole FQDN), then yes, it's using WINS. If not, since the subnet is
directly connected, then it's going to broadcast on that subnet for the
name. If using WINS, pinging a single name will check LMHOSTS first then
WINS, but all before DNS.
