DNS & DHCP

[Chris C]

Quick question:

I'm running a W2K server with AD, and DNS (with
forwarders to our ISP) and DHCP servicing the XP Pro and
98se workstations.

On the XP clients I point DNS at the server. On the 98
workstations I point DNS directly at the ISP.

In the DHCP settings, in 'Scope Options' I can specify a
DNS address (labelled 006: DNS Servers)

Should this address be the ISPs or the address of that
server on which DNS and DHCP is installed?

Thanks

What we do here is enter both the private DNS addresses
and public (ISP) DNS addresses. However, the private
addresses are at the top of the list. This way your DHCP
clients have plenty of secondary DNS's to query if they
happen to need them.

The scope option you mention will set the DNS server for any DHCP client
that receives an ip address from the DHCP server. There isn't a simple way
to configure DHCP so that one group of clients get one batch of options
while another gets different options.

I'd set the option to your internal server and use it for all of your
client regardless of OS. If you really want the Win98 machines to use
external (ISP) DNS servers set those manually which, if I recall Win98
behaviour correctly, will override the DHCP setting.

OK, seeing as you ask (-:

I've added the address of the local DNS server to the top
of the list in DHCP and letting the XP machines pick up
the address automatically. For now I'm leaving the 98se
machines as they are, pointing directly at the ISP. It's
worked fine for several years so if it ain't broke...

I would change the W9x machines too. If you;re using the DSClient, you'll
need the internal DNS. Besides, why have separate configurations for your
workstations? Isn't that administrative overhead and non-consistency in a
design? Just keep consistent. It eliminates many problems down the line.

I agree with Ace here. Keep it simple - one config for everything.
However, like you stated Chris, if it ain't broke...
