Using the Ensim Pro DNS server as a slave name server

If you are hosting Web sites on a server farm comprising many Ensim Pro servers and other business servers, it may be more efficient from an organizational point of view, to have all the zones created on one single central server in the farm, regardless of which Ensim Pro server hosts the domain. In this scenario, you may want to nominate one server, for example nameserver.isp.net as the master name server and set any Ensim Pro server, for example s1.isp.net on which you are creating a domain, as the slave server that obtains updates from the master server.

Ensim Pro creates a slave zone on the Ensim Pro server s1.isp.net, and configures it to obtain updates from the master server, nameserver.isp.net.

- Important: Before you create the site, you must create the zone on the master server nameserver.isp.net, otherwise, Ensim Pro will not be able to add the required records inside the master zone. Further, the master server must be configured to allow the slave s1.isp.net to obtain updates from the master. If you want Ensim Pro to add records to this zone, you must also allow s1.isp.net to update the zone that resides on nameserver.isp.net.

Assuming that you want to configure an external server nameserver.isp.net as the master name server and the Ensim Pro server s1.isp.net as the slave name server for a domain named myfirstcustomer.com, perform the following steps:

1. In the shortcuts section of the Home page
   , click Add IP-based Site or Add Name-based Site (Sites section).

2. On the Add Site form, click Advanced.

3. In the Master Name Server field (DNS section), enter the host name of the external server nameserver.isp.net.

4. Note: The external server can be any server running an implementation of the DNS protocol.

4. In the Slave Name Server field (DNS section), enter the host name of the Ensim Pro server s1.isp.net.

5. Complete the Add Site form and click Add Site.

Ensim Pro automatically creates the slave zone myfirstcustomer.com and zone records for the domain. To verify, click Zones (DNS) in the shortcuts section of the Home page.
