NT DNS not resolving external addresses

I am trying to get my NT DNS working properly so I can
migrate to WS2K3.  One problem I can't seem to get beyond
is that the DNS doesn't resolve external addresses on the
Internet and I think it should.  For example, if my
clients have my internal DNS address and an external DNS
server I can ping www.yahoo.com.  If I only have the
ijnhternal DNS IP address listed it can't resolve the
name.  Shouldn't DNS resolve all names for me without the
individual client workstations going to the external
nameserver for resolution?

Thanks,

PaulW

No.  DNS only can resolve names fro domains it is authoritative for
(or knows about).  If the domain has no records on the DNS server, it
can't resolve for that domain.

That's why you configure DNS forwarders on your internal systems
(which you apparently have not), so all unresolved queries get
forwarded to the next DNS in line.

IN the DNS management console, click on the properties of the DNS server. On
the Forwarders tab configure your ISP's DNS as forwarders.

Could you clarify the "it can't resolve it" part?

Are you using nslookup? Might I suggest you download and use Netdig from
www.mvptools.com to check your DNS resolution, it doesn't append suffixes
from the system resolver like nslookup does, and it doesn't perform a
reverse lookup on the DNS IP every time you make a query with it. It only
requires you have .NET framework installed if you run netdig from a local
disk. If Netdig is run from a network drive you have to adjust the trust on
the Netdig.exe and netdig.com files using the adjust trust wizard in .NET
framework.
