Hello,

I want to set up a conditionnal forwarder for a specific zone "zone.example.com" but when I'm adding a conditionnal forwarder for this zone, I got a :
"Unable to resolve" and a "The server with this ip address is not authoritative for the required zone".

I can click on "OK" but I afraid of the result.

The server is a DNS server we have on an another site and have the autority on this specific zone".

    Hello,

    Just to keep you inform, it's ok.

    The "unable to resolve" and "The server with this ip address is not authoritative for the required zone" are messages that can be ignored if you're sure about your operation (open port on firewall between the servers, etc...)

    So I deleted the zone.net, add the conditional forwarder for this zone and when I'm clicking on "OK" the red cross beside"The server with this ip address is not authoritative for the required zone" became green.

    Thanks

    Hi,

    In regards to your issue, here're my suggestions:

    1.First, You can use 'nslookup' command to test if the DNS server you wanted configured as conditional forwarder can query DNS names in the 'zone.example.com' correctly.

    1. When configuring condiftional forwarder, you should type the fully qualified domain name (FQDN) of the domain for which you want to forward queries. It seems that the '.net' is not a FQDN of the domain.

    For more details concerning configure conditional forwarder, you can refer to the following link:

    If my answer is helpful to you, please remember to mark them as answer. Thank you!

    Best regards,
    Gloria

    Hello,

    Yes, the conditional forwarder I want to configure can query DNS name in the zone.example.com. It's the DNS who's hosting this zone.

    When configuring condiftional forwarder, you should type the fully qualified domain name (FQDN) of the domain for which you want to forward queries. It seems that the '.net' is not a FQDN of the domain.

    Yes I'm writing well the FQDN of the domain. And yes the ".net" is a FQDN of the domain.
    We'll take this as example : zone.net, it's more accurate.

    Actualy, I already have a zone.net in my DNS because we were resolving the zone.net by a direct zone.
    But we do not have the update so we want to do this with conditinal forwarder.

    Thanks
