Very likely, although I don't know too much about how 2k Server does its
thing. This box hands out DHCP addresses to the various Windows
workstations and dynamically updates the DNS to match, so there's clearly
some magic going on. Hence the desire to delegate all these reverse lookups
to the 2k machine.

Might try that. Although I don't know if Bind will like being a secondary
for 10.1.128 when it's already the primary for 10.1 (?)

I will definitely do this.

That sounds useful -- hundreds or near-identical CNAME lines in the zone
file is clearly not a good thing.
Thanks for the help,
