Passing through DNS requests?

[Doward]

So I've got a DNS server upstream from a Samba server (named John). The Samba server passes DHCP to a small LAN.

I've got eth1 connected to the small LAN, and eth0 is on the larger LAN where the DNS server (Windows based) resides

I've got F10 set up, with Samba, DHCP, and Firestarter.

I can access the internet no problem - and I can ping from the small lan to the DNS server (chucky)

How can I set it up so that computers I hook up to my samba server (which hosts my PXE booting, btw) can also ping chucky (teh DNS server upstream from the Samba server) via hostname?

Pinging everything via IP address works fine. I'm trying to figure out a way for the DNS server to pass information through the Samba server to the clients connected to the Samba server.

Try setting up dnsmasq on the Samba box, which is a forwarding DNS cache service.

In order to pass DNS requests through, do I need to use the DHCP built into DNSmasq?

I ask because I've got DHCP set up with PXE boot on the samba server. How about this - is there any way I can declare that a specific IP is associated with computer 'chucky' on Samba, so that when a client connected to Samba automatically goes through to the ip? I can ping the IP address from behind the Samba server, but I can not ping the hostname.

I just noticed that my Samba box doesn't seem to be registering with my DNS server. How do a make certain that my Samba box updates the DNS server?

Further research has brought me to a 'net ads register dns' command.

Just to make clear, this is a Samba box in a Windows Server 2003 network. I'll try this out tomorrow and see what happens.
