domain delegation and "dynamic" DNS

[Jim Ault]

I have two questions  (BIND 8.2.1, Solaris 5.7)

1) Delegation 

I have just finished configuring a software package on NT 4.0 to 
serve a DHCP pool of addresses and also to serve a "dynamic" DNS zone for
that pool of addresses.  That part works now, as verified from within
the package, and from nslookup, when pointed directly at this NT server.

However, I have added some delegation records to my BIND 8.2.1 server to
delegate this subdomain to the NT box, with the intent that both forward
and reverse lookups would recurse through my primary BIND server to the
NT box to get the desired data.  

But my primary server does not appear to be recursing properly 
to the delegated server.   When I tested the NT box for DNS lookups
by directing nslookup to that server IP address, and testing forward and
reverse lookups, the both worked.  But when I give the same forward and
reverse lookups to my primary server, the response is "no such domain".

Am I missing something?  I have attempted to delegate both the forward
and reverse lookups with the lines shown below (in the appropriate files).
yes, I have BIND&DNS 3rd edition, and I followed the examples as best I
could.  Perhaps the extra A record is causing me trouble?
The <A.B.C.D> is a std IP address, along with C.B.A as you would expect
in a reverse zone.

dhcp.crd.ge.com.    IN      NS      dhcp1.dhcp.crd.ge.com.
                            A       A.B.C.D
dhcp1.dhcp.crd.ge.com.      IN  A   A.B.C.D

C.B.A.IN-ADDR.ARPA.   IN      NS      dhcp1.dhcp.crd.ge.com.

2) Dynamic DNS

Let's also say that this NT box is sending "dynamic DNS updates" to my
BIND 8.2.1 server as well as to itself (running some NT DNS server).

I get errors like this:

===
Aug 26 11:36:32 crdns named[25570]: rcvd NOTIFY(C.B.A.in-addr.arpa, IN,
SOA) from [A.B.C.D].53
Aug 26 11:36:32 crdns named[25570]: rcvd NOTIFY for
"C.B.A.in-addr.arpa", name not one of our zones
Aug 26 11:36:53 crdns named[25570]: rcvd NOTIFY(dhcp.crd.ge.com, IN, SOA)
from [A.B.C.D].53
Aug 26 11:36:53 crdns named[25570]: rcvd NOTIFY for "dhcp.crd.ge.com",
name not one of our zones
===

What does this mean in terms of delegation (question I asked above)
regarding a domain or a subdomain.  I did the delegation because I knew
the NT box would want to be "master" of something, so I gave it a small
subdomain to be master of.  

Can my bind 8.2.1 server be the master of A.B.*.* and the forward
and reverse name zones that go with it, while also allowing this NT
dynamic DNS program to push this data in to my BIND server without
delegating a subdomain?  Does this mean that the NT box thinks it is the
master of that primary zone?  (I don't think I can allow that..)

Thanks in advance for any help...
