   Table 3-8 DNS Internal Root Server Configuration

   Option	Description
   DNS Domain Name	The DNS domain in which the Netra server resides. This name is used for two purposes:   as a contact address for the DNS administrator. when creating the DNS server record for this server for any primary domains for which it is responsible. The domain name is assumed to be fully-qualified whether or not you enter a period at the end. Example: cartoon.net.
   DNS administrator's user name	Enter the name or alias of the local user (for example, root) who is responsible for DNS. All DNS database files contain a contact address - the address for this server consists of the name of this user, the name of the Netra server, and the domain name entered into the domain field.
   Internal Root Server / IP Address	This field is only relevant if the internal network has other DNS internal root servers (an entry for this server is created automatically). If there are none, leave this field blank. Enter the fully qualified host names and host addresses of each DNS internal root server.
   DNS Server / IP Address	This field is only relevant if the internal network has non-root DNS servers that reside in the top-level domain and to which this server delegates responsibility for primary domains. If there are none, leave this field blank. Enter the fully qualified host names and host addresses of each DNS server. If a server has more than one IP address, create an entry for each address
   in-addr.arpa Domain Name / DNS Server	This field is only relevant if this root server delegates responsibility for reverse maps (in-addr.arpa domains) to other DNS servers on the internal network. If it does not, leave this field blank. Create domain name/name server entries for the in-addr.arpa domains maintained on the other DNS servers. Use fully qualified names in both cases.

   Create the primary domain corresponding to the name entered in the DNS Domain Name field with the "Add a Primary Domain" form.

The Operation Successful page displays information about the server configuration, and if the Netra server is not configured to be a DNS client of itself, informs you of this and provides a link to the DNS client configuration form.

If you change the name of the domain in which the server resides, the DNS resource files for the primary domains are updated with respect to the contact address and the name server address of the Netra server. Review the individual primary domains to update any other references to the old domain name.
