Specifying a secondary name server

- Note: If your domain name registrar or service provider maintains your domain information on their DNS servers, you do not need to do anything with the DNS settings of Ensim Pro; the settings shown in the DNS section of the Appliance Administrator GUI are not used. For more information, see:
  Introduction to DNS and name servers
  Using Ensim Pro as a DNS server

If you are using Ensim Pro as a DNS server, you can specify the name of the secondary name server through the Appliance Administrator GUI.

A secondary name server is necessary for redundancy. If the primary name server is not operating, the secondary name server translates the domain names so that your business functions are not interrupted.

The secondary name server transfers transaction data from the primary server and caches it according to parameters you specify in the Start of Authority (SOA) record.

To specify a secondary server:

1. Stop the Domain Name Server.

2. In the shortcuts section of the Home page
   , click Configuration (DNS section).

3. On the Configuration: Name Servers form, locate Secondary Server and in the Actions column, click .

4. In the Secondary Server/Virtual DNS Setting form, click the Secondary Server option.

5. In the Server Name field, enter the fully qualified name of the secondary DNS server you will be using.

6. Click Save.

7. Restart the Domain Name Server.

8. Note: After making changes to the domain name server, you must restart the name server for your changes to take effect. Be aware that it may take up to 48 hours for your DNS changes to be visible on the Internet.
   However, if you are not using Ensim Pro as a DNS server, these settings are not used.
