Configuring the DNS Server as a Secure Caching-only 
DNS Server 
The DNS server on the perimeter network will be in direct contact with Internet hosts. These 
hosts can be DNS clients that query the perimeter network DNS server for addresses of 
publicly accessible domain resources.  They can also be DNS servers on the Internet that the 
caching-only DNS server contacts to resolve Internet host names for internal network clients. 
In this example, the DNS server will act as a caching-only DNS server and will not host public 
DNS records for the domain. 
Perform the following steps on the perimeter network DNS servers to configure it as a secure 
caching-only DNS server: 
1. Click 
Start and point to Administrative Tools. Click on DNS
2. In 
the 
DNS management console, right click on the server name in the left pane of the 
console and click Properties
3.  In the DNS server’s Properties dialog box, click on the Root Hints tab. The entries in the 
Name servers list are for Internet root name servers that the caching-only DNS server 
uses to resolve Internet host names. Without this list of root DNS servers, the caching-
only DNS server will not be able to resolve the names of machines located on the 
Internet.
