usage of internet DNS server together with an internal win2000 ADSDNS server

[Oliver Graeser]

Hej,


might be a strange or silly problem, but I didn't find any information
about this problem, so hoping for friendly souls here...

We have a Windows 2000 Server in our network, using ADS for (only
internal) exchange server usage. As it happens during the DC promotion,
there is a dns server set up for our domain
(neuwied.limbach-gebaeudereinigung.de, some isp runs a
www.limbach-gebaeudereinigung.de for us), in this domain we use only
192.168.0.* addresses. Now we changed our internet connection to dsl and
bought a little firewall router to connect the pcs to the internet. So
far so easy, if we know the IPs of the servers we want to visit. But DNS
is tricky, because if I enter the address of an internet dns server into
the dns server field of the ip setting (as an addition of the
192.168.0.1 dc dns), the client seems to use only the first address. So,
if i put the 192.168.0.1 address first, I don't have internet name
resolving, if I put the internet dns first, the client doesn't find the
ads and I can't log onto the server anymore.

Then I thought about telling the w2k-dns to ask the internet dns for
names it cannot resolve itself, but there my knowledge ends... Because
all tutorials tell me how to set up a forward-lookup-zone or the
reverse-lookup-zone (what is just a make-the-right-mouseclick that is
pretty useless), but no tutorial tells me what i need to tell my dns
which other dns to ask.

A lot of thanks in advance;-)

All clients must use the internal DNS server only oryou'll have problems and
errors on your own network. Your internal DNS should already be able to
resolve names it does not own, if it is not a Root Server. If it is a root
server delete the root "." (dot) forward lookup zone. Then refresh the DNS
console or close and reopen it, then you can configure a forwarder to you
ISP's DNS on the Forwarders tab of the DNS server properties sheet.
