I have an internal dns server for our windows domain, and an external dns server for pur public address space.

For local domains it is necessary to add host entries in both the windows domain and on the linux server.

is there a way to configure the windows dns server running on win2k to look at the external dns sesrver if it does not find an address for our local domain on the windowx box.

Example: is on the external network at a colo space. On the windows server if you do not add it is not resolved. So to fix that we have to keep to databases up. We would only like to keep 1 database for the external hosts.

I already am forwarding unknown domains to the external server.

Thanks for any info.

    You could take a zone transfer from to your internal DNS Server - assuming of course that you named your internal domain something different to your external domain.

    Its preety much easy. Use Forwarders tab on local DNS server to pass queries not related to local LAN.

    Yes, that is one way to do it. Both domains are the same. I was hoping that there was some way to configure the windows dns server to send on unknown hosts for the same domain to the external server.

    Afraid not.

    When you set up a master zone on a DNS Server, regardless of operating system, you are telling that DNS server it knows absolutely everything about the zone.

    If the ability to forward unresolved requests for its own master zones were added in it could cause huge problems in the form of loops in the DNS system; where two systems continually bounce requests between each other, always unresolved.

    Although it's generally not a very pleasant answer - To get around the problem of having to update multiple zones don't use the same domain name on two different networks.
