DNS - DHCP Fedora 6 update Refused


I configured a Linux DHCP Server. Windows Client gets an IP, but doesn't succeed to register in DNS. When I look in the tcpdump I see the following error:

11:44:48.368041 IP xxx.xxx.xxx.xxx 1135 > xxx.xxx.xxx.xxx .domain: 22844+ SOA? svctag-j9f9p0j.xx.xxx.xxxxx.xxx. (49)
11:44:48.368378 IP xxx.xxx.xxx.xxx .domain > xxx.xxx.xxx.xxx .1135: 22844 NXDomain* 0/1/1 (138)
11:44:48.369188 IP xxx.xxx.xxx.xxx .1135 > xxx.xxx.xxx.xxx .domain: 5694 update [1a] [2n] SOA? xx.xxx.xxxxx.xxx. (105)
11:44:48.370189 IP xxx.xxx.xxx.xxx .domain > xxx.xxx.xxx.xxx .1135: 5694 update Refused- 1/2/0 (105)
11:44:48.390818 IP xxx.xxx.xxx.xxx .netbios-ns > xxx.xxx.xxx.xxx .netbios-ns: NBT UDP PACKET(137): QUERY; REQUEST; UNICAST
11:44:48.391169 IP xxx.xxx.xxx.xxx .netbios-ns > xxx.xxx.xxx.xxx .netbios-ns: NBT UDP PACKET(137): QUERY; POSITIVE; RESPONSE; UNICAST

I just configured dhcpd.conf. Do I need to configure something else ?

ddns-update-style interim;
default-lease-time 90000;
max-lease-time 720000;

subnet xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx {
option routers xxx.xxx.xxx.xxx;
option subnet-mask xxx.xxx.xxx.xxx;
option domain-name "xxx.xxx.xxx.xxx";
option domain-name-servers xxx.xxx.xxx.xxx, xxx.xxx.xxx.xxx;
option netbios-name-servers xxx.xxx.xxx.xxx, xxx.xxx.xxx.xxx;
range xxx.xxx.xxx.xxxxxx.xxx.xxx.xxx;
}

well yes, you actually need to configure it completely.... you've only configured dhcp right? how has bind got any idea at all about that? refer to standard documentation to get strated. this also looks generally useful http://www.ops.ietf.org/dns/dynupd/s...dns-howto.html

I read the documentation, but it looks that this is the way to configure a DNS server in Linux.

I only configured DHCP on linux cause I want to send DNS requests / updates to a Windows DNS Server who is already running.

When I look in the error message it looks that is has something to do with security on a DNS zone on the Windows Server, but I don't know where to look.
