dhcp not updating dns server

[James Dinkel]

Well I tried this on Ubuntu Hardy and at least now I'm getting something
showing up in tcpdump:

17:12:27.079892 IP 192.168.101.254.60433 > 192.168.100.2.53: 46870+ PTR?
5.50.168.192.in-addr.arpa. (43)
17:12:27.082444 IP 192.168.100.2.53 > 192.168.101.254.60433: 46870 NXDomain*
0/1/0 (133)
17:15:43.605453 IP 192.168.100.2.138 > 192.168.101.255.138: NBT UDP
PACKET(138)

It's virtuall the same configuration.  Here is my config file:
-------------------------------------------------
ddns-update-style interim;
ignore client-updates;
zone COMPANY.COM. {
    primary 192.168.100.2;
}
zone 100.168.192.in-addr.arpa. {
    primary 192.168.100.2;
}


# option definitions common to all supported networks...
option domain-name "company.com";
option domain-name-servers 192.168.100.2, 192.168.100.3;

default-lease-time 6000;
max-lease-time 7200;

# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;

# This is a very basic subnet declaration.

subnet 192.168.100.0 netmask 255.255.254.0 {
  range 192.168.100.100 192.168.100.200;
  option routers 192.168.100.1;
}
-------------------------------------------------

I just edited the default dhcpd.conf file in Ubuntu.  It looks identical
except there is an "authoritive" directive in this one.  I have not tried it
with that "authoritative" commented out.  The updates are still not showing
up on the dns server and I would prefer to do this on Red Hat but at least
I'm getting something in the tcpdump output.
