Are you using a special Dynamic DNS update client, or relying on some
functionality in dhclient? Is the DHCP server a MS DHCP server, that
could update AD/DNS for you? It seems from your ping that the DNS entry
which your Win2k side registers lingers for a little while, long enough
for you to reboot into FreeBSD. On Win2k shutdown, the address is
de-registered (unless configured differently) from DDNS, so unless you
are using a DDNS update client to re-register on the FreeBSD side, the
registration won't work for too long. But the deregistration can take a
few minutes, depending on how busy the server is, so you might get
response from your entry for a few minutes after Win2k shutdown.
