newbie: dynamic dns and dhcp on suse 8.2

[remanance]

Hi,

I'v configured bind9 and dhcpd as given in the
/usr/share/doc/packages/dhcp-server/DDNS-HOWTO.txt. The windows
clients are accepting all IP address, wins, gateway settings, but
dhcpd is not dynamically updating named.

I get the folloinwg message:

Mar  5 16:23:02 penguin dhcpd: DHCPREQUEST for 192.168.2.50 from
00:00:21:d9:e0:cb (tecdir) via eth1
Mar  5 16:23:02 penguin dhcpd: DHCPACK on 192.168.2.50 to
00:00:21:d9:e0:cb (tecdir) via eth1
Mar  5 16:23:05 penguin dhcpd: Unable to add forward map from
tecdir.rre.lan to 192.168.2.50: timed out

I would appreciate and help. Thank you in advance,

Kartik
