hi ARC, thanks for the input, iv now got DHCP updating as it should now i need to get the DNS server to resolve domains for me.
did a bit more playing i now have DHCP updating the forward and reverse DNS fine now, i cant seem to get the DNS server to resolve out side domains to IPs
if i do a nslookup
www.google.com from dhcp client i get
Code:
can't find server name for address 192.168.0.2: timed out
default servers are not available
server:unknown
address: 192.168.0.2
unknown cant find www.googel.com: no responce from server
the DNS server will resolve fine
Code:
nslookup www.google.com
Server: 127.0.0.1
Address: 127.0.0.1#53
Non-authoritative answer:
www.google.com canonical name = www.l.google.com.
Name: www.l.google.com
Address: 64.233.183.99
Name: www.l.google.com
Address: 64.233.183.104
Name: www.l.google.com
Address: 64.233.183.147
if i put in a google IP all is ok google page will come up i cant ping it search on it.
here are my final config files as they stand

any one looking over this problem with above scripts are missing " on the keys, missing . with in the zone reverse file few minor tweaks on dhcp file almade allow client-update in dhcpd.conf.
if any one can help me getting the clients to retrive domain info from the DNS this would be grate.
thanks for any help
robert
