DDNS with BIND and ISC-DHCPD


I'm having real problems getting DDNS to work.

named.conf
Code:
include "/etc/namedb/rndc.key";
options {
        directory       "/etc/namedb";
        pid-file        "/var/run/named/pid";
        dump-file       "/var/dump/named_dump.db";
        statistics-file "/var/stats/named.stats";
        listen-on       { 10.203.1.7; };



        forwarders {
                10.203.1.4;
                10.203.1.5;
                };
};

// If you enable a local name server, don't forget to enter 127.0.0.1
// first in your /etc/resolv.conf so this server will be queried.
// Also, make sure to enable it in /etc/rc.conf.

zone "." {
        type hint;
        file "named.root";
};

zone "0.0.127.IN-ADDR.ARPA" {
        type master;
        file "master/localhost.rev";
};

zone "1.203.10.in-addr.arpa" {
        type master;
        file "master/1.203.10.in-addr.arpa";
        allow-update { localhost; };
};

zone "enodis.com" {
        type slave;
        masters {
                10.0.1.1;
                };
        file "/etc/namedb/enodis.com.hosts";
        };
zone "viscount-catering.co.uk" {
        type master;
        file "/etc/namedb/viscount-catering.co.uk.hosts";
        allow-update { localhost; };
};
dhcpd.conf

Code:
#Global
option subnet-mask 255.255.0.0;
option domain-name "viscount-catering.co.uk";
option routers 10.203.0.1;
option domain-name-servers 10.203.1.7, 10.203.1.5;
ddns-domainname "viscount-catering.co.uk";
ddns-rev-domainname "viscount-catering.co.uk";
default-lease-time 2400;
max-lease-time 7200;
ddns-update-style interim;
# Local Clients

subnet 10.203.0.0 netmask 255.255.0.0 {
        authoritative;
        allow client-updates;
        allow unknown-clients;
        ddns-updates on;
        ddns-update-style interim;
        range 10.203.4.1 10.203.4.254;
        }

# Client Reverse

key rndc-key {
        secret <blah>;
        algorithm hmac-md5;
        }

zone viscount-catering.co.uk. {
        primary 10.203.1.7;
        key rndc-key;
        }
When a client connects, it gets the dhcp lease ok, but it wont update the DNS. i get

May 25 14:31:25 intranet dhcpd: Unable to add forward map from prodctrl1.viscount-catering.co.uk to 10.203.4.81: timed out

I cant see what is wrong, and nothing i've searched for seems to give me any clues as to what may be wrong.

Doesn't the named.conf need the ddns-update-style interim line?
