Need help - AD failing to register with BIND 9.2.3 DDNS server

[TZ]

Trying to set up a W2k3 AD sevrer to work with a BIND 9.2.3 DNS server
- but getting the following error message on the AD server


The system failed to register host (A) resource records (RRs) for
network adapter
with settings:

   Adapter Name : {}
   Host Name : chgdcinet1
   Primary Domain Suffix : diamondcluster.net
   DNS server list :
     	10.1.1.30
   Sent update to server : <?>
   IP Address(es) :
     10.1.1.20

 The reason the system could not register these RRs was because the
DNS server contacted refused the update request. The reasons for this
might be (a) you are not allowed to update the specified DNS domain
name, or (b) because the DNS server authoritative for this name does
not support the DNS dynamic update protocol.

 
Not seeing anything logged on the unix server - or being denied - so
at a loss

My named.conf file is as follows


#named.conf
options {

	directory "/var/named";
#    query-source address * port 53; 

	notify yes;
	pid-file "/tmp/named.pid";
};

logging {
        channel default_file {
                file "/var/adm/named" versions 9 size 20m;
                print-time yes;
                print-category yes;
        };
        channel bitbucket {
		null;
        };

        category default { default_file; default_syslog;
default_debug; };
        category lame-servers { bitbucket; };

};

	allow-update {

	check-names ignore;
	};

and a sample zone file

$ttl 38400
diamondcluster.net.	IN	SOA	ritchie. hostmaster.diamondcluster.com. (
			1092919564
			10800
			3600
			604800
			38400 )
diamondcluster.net.	IN	NS	ritchie.


Not sure whatis wrong - would appreciate any help as I see no errors
or any logs of sorts in the named or messages file or even syslog.
