Changing the name of the primary 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 change the primary name server through the Server Administrator control panel.

The Primary name server, as the name implies is the primary authoritative server for the domain. The Primary name server sources data authoritative for the zone from a file called the zone data file.

When you add a zone to the DNS server, you must provide at least two name servers for the zone: a primary name server and a secondary, or backup, name server.

To change the primary DNS server name:

1. In the shortcuts section of the Home page, click Name Servers (DNS section). The list of name servers are displayed.

2. Locate Primary Master in the server list and in the Actions column, click . The Primary Master Setting form opens.

3. In the Primary Master FQDN field, do one of the following:

• If you want Ensim Pro to always use the most current host name, leave the field blank.

• If you want to specify a host name, enter the fully qualified name of the DNS server you will be using.

4. Click Update.

5. Note: If you are not using Ensim Pro as a DNS server, these settings are not used.
