Operating Systems Linux Red Hat DHCP & DNS - Clients get IP but don't register in DNS Post 302594357 by FireBIade on Tuesday 31st of January 2012 05:38:29 AM

DHCP & DNS - Clients get IP but don't register in DNS

I am trying to setup a CentOS 6.2 server that will be doing 3 things DHCP, DNS & Samba for a very small office (2 users). The idea being this will replace a very old Win2k server. The users are all windows based clients so only the server will be Linux based.

I've installed CentOS 6.2 with DHCP, BIND 9 and also Webmin to aid config. DHCP seems to be working no problem with the WinXP test machine however it doesn't seem to register itself with the DNS server.

NSLookup on the XP client pauses and then says
DNS request timeout
timeout was 2 seconds
*** Can't find server name for address 10.0.0.1: Timed out
*** Default servers are not available
Default Server: UnKnown
Address: 10.0.01

I have configured reverse DNS. I've heard it's something to do with getting the DNS server to trust the DHCP server but I'm not clear on how to go about that.
