DHCP server and Windows 2003 DNS

Hello!  I am struggling with an issue on my local network.  I am using
the DHCP server on a Linux box to assign IP addresses.  I have two
subnets - on one subnet I am using W2K3 DNS, on the other I am using
BIND, running on the same box as DHCP.  I've configured DHCP to update
DNS.  It seems to work fine for BIND, but for the W2K3 DNS the IP
addresses that are being added to the reverse map are in the form of
192.168.192.168.0.1 - it's prepending 192.168. to the actual IP address.
 Forward mapping is functioning appropriately.
I've Googled this problem extensively and haven't found anything.  Here
is my dhcpd.conf:

allow client-updates;
allow unknown-clients;
authoritative;
ddns-updates on;
ddns-domainname "massivegeek.local";
ddns-update-style interim;
include "/etc/rndc.key";

# Trusted Network
subnet 192.168.0.0 netmask 255.255.255.0 {
        ddns-rev-domainname "0.168.192.in-addr.arpa";
        option domain-name "massivegeek.local";
        option domain-name-servers 192.168.0.3, 192.168.0.1;
        option broadcast-address 192.168.0.255;
        option routers 192.168.0.1;
        range 192.168.0.100 192.168.0.254;
        option smtp-server 192.168.0.1;

}
# Untrusted Network
subnet 192.168.1.0 netmask 255.255.255.0 {
        ddns-rev-domainname "1.168.192.in-addr.arpa";
        option domain-name "massivegeek.local";
        option broadcast-address 192.168.1.255;
        option domain-name-servers 192.168.1.1;
        option routers 192.168.1.1;
        range 192.168.1.50 192.168.1.254;
        option netbios-name-servers 192.168.1.1;
        option smtp-server 192.168.1.1;
        }
zone massivegeek.local. {
        primary 192.168.0.3;
        }
zone 1.168.192.in-addr.arpa. {
        primary 192.168.1.1;
        }
zone 0.168.192.in-addr.arpa. {
        primary 192.168.0.3;
        }


I appreciate any insight you all can give!

Nolan
