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 Server 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 Server 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:
Stop the Domain Name Server.
In the shortcuts section of the Home page, click Name Servers (DNS section).
Locate Secondary Server in the server list and in the Actions column, click . The Secondary Server Setting form opens.
In the Secondary Name Server field, enter the fully qualified name of the secondary DNS server you will be using.
Click Update.
Restart the Domain Name Server.
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.
