Hi,
I hope that someone will help me out with this problem
that i'm facing. I've a win2k domain controller(Zeus) with
an additional domain controller(Ramses) setup on my LAN.
The Domain controller(Zeus) has an DNS server that is
active directory integrated on it. the ADC(Ramses) too has
an DNS server that is secondary to Zeus. Now the problem
is that when i run nslookup on any machine on the LAN it
points correctly to the main DNS server i.e
zeus.domain.com and gives out its IP too, but if i run
nslookup on the ADC which ahs two NIC cards one connected
to the local LAN and another to the ISP, it points to the
ISP's DNS server but not to the local DNS server. The
settings on the NIC cards is, the local LAN has an IP
address and the DNS server entries are prefered is the
Domain controller DNS server IP address and in the
secondary its its own IP address. How do i resolve this
conflict and make the ADC with 2 NIC cards point to the
internal DNS server first before sending a query to the
ISP dns server?????. I hope what i have written here is
understandable, please help me out of my situation, as the
secondary DNS server has an Proxy server too running on it
and this is giving problems in the LAN while they browse.

Thanks in Advance,
Crownu
 
You did not indicate what the settings are on external NIC (LAN). I assume
it's now pointing to your ISP for DNS. Try to follow this rule: Don't use
your ISP DNS anywhere in TCP/IP configuration. IF you must use your ISP DNS,
use it as a Forwarder.

Follow what Deji said: Internal machines must point to (resolve from)
ONLY the INTERNAL DNS server (set).

Let the internal DNS servers forward to the router or ISP that handles
the actual recursion of the Internet.

But it also sounds like you may not be registering the DNS name/
address of your server most effectively....

So, if you run DNS on a multihomed machine, you can 1) control
which NICs/addresses it will offer DNS on by using the DNS MMC.
2) make sure the DNS server only registers it's MAIN (internal) name
using the internal NIC's IP address.

#2 can be done on each NIC properties by adjusting the Advanced\DNS:
"Suffix" (I use cable.learnquick.com & dsl.learnquick.com on the outside
of my routers) and by checking or unchecking the "register this connection's
addresses in DNS".
