dhcp and bind

Hi!

I want to setup dhcp and bind in the way so dhcp can update bind records of users on the lan so they can access machines by its hostname. I have googled and I found some instructions but know I have the following problem:
from the syslog:
-------------------
Apr 17 08:30:04 mig29 dhcpd: Unable to add forward map from MASTER.workgroup to 192.168.10.249: timed out
Apr 17 08:30:04 mig29 dhcpd: DHCPREQUEST for 192.168.10.249 from 00:0c:6e:f1:f3:48 (MASTER) via eth1
Apr 17 08:30:04 mig29 dhcpd: DHCPACK on 192.168.10.249 to 00:0c:6e:f1:f3:48 (MASTER) via eth1

my workgroup.zone:

mreza	IN	SOA	localhost. root.me.homelinux.net. (

			604800
			3600 )
			NS	localhost.
$ORIGIN mreza.
$TTL 1800	; 30 minutes
-----------------

Both named and bind runs on the same server (localhost).
What am I doing wrong here?
