I have configured Windows DNS server to service incoming internet traffic and set the DNS settings on the machine to local IP. The Windows DNS forwards requests to Cisco GSS for certain A records.

Now when I ping any internet domain/hostname from a PC whose DNS is set the above mentioned DNS server, the names get resolved such as etc.

Windows DNS do not have any forwarders. All the root hints have been removed. Any clues ?

a. Enter a name for your answer group in the Group Name field.

b. (Optional) Choose an owner for the answer group by clicking the Group Owner drop-down list and selecting a GSS owner from the list.

c. Select an answer group type by clicking one of the three option buttons. Once you select an answer group type, only answers of that type (VIP, NS, or CRA) can be added to the group:

VIP-Virtual IP (VIP) addresses associated with an SLB as such the Cisco CSS, Cisco CSM, Cisco IOS-compliant SLB, LocalDirector, web server, cache, or other geographically dispersed SLBs in a global network deployment.

Name Server-Configured DNS name server on your network that can answer queries that the GSS cannot resolve.

CRA-Content routing agents that use a resolution process called DNS race to send identical and simultaneous requests back to a user's D-proxy.

d. Click Next to use the Answer Group Page 3 of the wizard to configure answers for your answer group.

Its working now.

Even though root hints are removed, its gets automatically refreshed (default behavior).

To suppress any outgoing name queries, new root zone '.' needs to be created in Windows DNS.
