Michael:
Heya. Each of the LAN machines gets a DHCP lease
from the DS box, with the DS box indicated as the DNS
server. Only the DS box has the /etc/hosts entries.
For example, in the /etc/hosts file it reads:
192.168.123.1 pc.private.network pc1
192.168.123.2 winnt.private.network winnt
I can see my WinNT Box (at .2) query the DS box
for a reverse-lookup (PTR?) for 1.123.168.192, and I cannot
see that the DH box replying with "pc.private.network".
Hope this helps clarify.
