Question : DNS Forwarder

Hello,

I try to forward a domain for example 'mysubdomain.mydomain.org' to a forwarder IP address using Windows 2003 server.

I have entered DNS domain and added IP addresses to forwarder IP address list. But when I hit apply I get this error message:

The server forwarders cannot be updated.
The zone already exists.

The domain I am trying to forward from is in Forward Lookup Zones on the same DNS server.

Thanks.

Answer : DNS Forwarder

Then you would first have to delete existing zone.
I would recommend that you avoid using conditional forwaders and try using stub zones. Stub zone will copy SOA, NS and A glue host records for nameservers. Even if IPs of nameservers change with stub zone everything will continue to work, with conditional forwarding you will have to change IP numbers.
