I have 2 name servers running and registered with static ip. I'm
running server 2000 on both name servers with DNS in Active Directory.
The DNS seem to work local just fine, because I'm able to do a nslookup
and get a reply back from both name servers. The problem I have is my
domain name never resolved on the internet. Not sure if it is the
router ( Netopia 3346n) config with SBC static ip's or if it is the
BlackICE firewall sofware stopping the DNS updates. Please need
to know where i should start looking for the problems.

Have you chosen to setup FORWARDING or are you using
physical recursion by these internal name servers?

If the former, then go to the DNS servers (command line) and
check that each of them can reach the forwarder DNS server
at your gateway or ISP by specifying it's IP....

If the firewall is blocking the internal server it will also not
work for NSLookup:

nslookup www.google.com IP.of.DNS.Forwarder

If you are using direct recursion then just check in a similar
manner for any known working DNS server on the Internet:

nslookup www.google.com 4.2.2.1

Checking the path from the internal DNS server to either the
forwarders OR external servers will prove the internal servers
can reach externals sources.

If you have a "." zone on your internal servers then you
need to delete that (to enable recursion and forwarders),
or if you have the DNS Server set to "disable recursion"
in the Advanced tab you need to uncheck that.

You need to clarify, does this mean you cannot resolve external IPs or are
you trying to use your two DNS server for Public Name servers?

IF you have black Ice on the DCs it's not going to work though, your going
to have to remove it from your servers.

If you're trying to use your local DNS for Public servers, the 3346n is
somewhat of a different critter to set up to do this. In the default mode,
even though you may have 5 public IP addresses, the only one that is
accessible from the internet is the Gateway address which is the router's
IP. It can be set up to allow incoming connections to each of the addresses
they gave you, I had to get Netopia to set it up for me and he told me how
to do it, but for the life of me its been two years and I don't have a clue.
I don't personally have one, but one of my clients does, and he wanted
incoming connections to each of the five addresses he has.
There may be a way to set the 3346n up in firewall mode and still allow
incoming connections to each of the IP addresses you have, but you really
need to contact Netopia and tell them what you want so they can you.

I am confused as to exactly what you're trying to do. Are you trying to host
DNS services on the internet witrh your internal DNS server? If AD I
wouldn't suggest it. Kevin and Herb gave you some good suggestions
otherwise.

But I am wondering... Do you mean your internal DNS servers can't resolve
your public domain name, such as www.yourdomainname.com?

If this is the case, is the internal AD domain name and the external public
domain name the same?

You can test this while using nslookup, change the server reference to an
external server and re-run the query. For instance, in nslookup, use:

server 4.2.2.2

That command tells nslookup to now use an external server to resolve the
query. If that works, then I would assume that the internal andexternal
domain names are the same. If such the case, simply creating a www record
under your own internal zone and give it the actual external IP address of
the ISP's web server will do the trick. Delegating 'www' under your zone
would be better; jsut provide the authorative nameserver(s) of your public
domain name.

If I wrong with my assumption, please follow the other suggestion.
