Box 1:  Firewall/DHCP Server/DNS (FreeBSD 5.3)
Box 2:  DHCP Client (FreeBSD 5.3R2)

When I boot Box 2, it gets its IP address, but DNS doesn't
get updated, so Box 2 is unknown to the LAN via its hostname.
If I boot a windows box (tested with 2000/XP), and I've tested with a
networked printer, they get an IP address, and DNS is updated
for those devices.

Any help would be appreciated.
Thanks
