DHCP/DDNS Doesn't Work with Netgear Devices

Hi,

I've got a couple of different Netgear devices on my network. A couple
of Print Servers, and a Wireless Access Point. None of these seem to
work correctly with DHCP/DDNS. Here's the error I get when one of the
Print Servers renews it's lease:

Mar 2 18:07:37 The-Tardis dhcpd: if IN A RAINBOW domain doesn't exist
add 43200 IN A RAINBOW 192.168.0.41 add 43200 IN TXT RAINBOW
"00ae82dfbe9eb18ce88e018bbd371de74d": timed out.

What's happened, is that the device name hasn't been made Fully
Qualified. Here's a working example:

Feb 27 09:06:18 The-Tardis dhcpd: if IN A eddieath.BogoLinux.net
domain doesn't exist add 43200 IN A eddieath.BogoLinux.net
192.168.0.49 add 43200 IN TXT eddieath.BogoLinux.net
"31f655e98e1282b88a57b03f6871813602": success.

As there's no way I can change the firmware in the Print Server, how
can I force either DHCPD or Named to add the Domain. I've tried the
following In my dhcd.conf, but it didn't make any difference.:

ddns-domainname "BogoLinux.net";

So, any thoughts.

Also, the AP doesn't doesn't even make any attempt to update the DNS.
How can I try and make this work as well.

Cheers,
Eddie
