Configuring for DNS
As an alternative to a host table on every system, some networks use a centralized
Domain Naming System (DNS) server to maintain name-to-IP-address mappings. You
may configure the SSR to reach up to three DNS servers. When doing so, you can also
specify the domain name the SSR uses for each DNS query and the order in which the SSR
searches for the specified DNS servers.
To configure the SSR for DNS servers:
1. Make sure there is a network connection to the DNS servers you want the SSR to use.
You can do so by sending a ping packet to those servers.
2. Start Configuration Expert if you have not already done so.
3. Open the configuration file you want to modify and then double-click that file’s
System Configuration object.
4. Select the DNS Configuration object.
A System Configuration DNS dialog Box similar to the following appears:

5. Specify which DNS servers you want the SSR to use by taking the following steps to
add those servers. When the SSR searches for DNS servers, it will do so using the
order in which those servers were added.
a. In the Domain text box, enter the name of the domain on which the DNS server
you want to add is an authority.
