By default, the DSfW installation configures a DNS server in the forest root domain's first domain controller, and introduces a new DNS Locator object in the tree. If you have already configured Novell DNS Server in the same tree, using the existing DNS Locator object is mandatory. You can do this by providing the existing DNS Locator context in YaST during DSfW Configuration. This will ensure that if DSfW is configured to serve an existing domain, the existing DNS Zone is extended with DSfW-specific DNS settings instead of creating a duplicate DNS Zone.
In an existing environment, specify the existing DNS Locator object. Otherwise, a new DNS Locator Object will be created with a new zone for the same domain name. This new duplicate zone will need to be manually merged into the existing DNS Zone using Novell DNS/DHCP Console. A tree can contain multiple DNS Locators. However, we recommend that you have a unique DNS Locator object per tree. This ensures that there are no duplicate DNS Zones in the tree and it enables the zones to be managed in the DNS/DHCP console.
We recommend that you create the DNS entries for the new DSfW servers before installing DSfW. This is because servers can resolve each other using the name and IP address when installing DSfW into an existing tree. If there are new DNS zones created for the DSfW domains, you should create these zones before the DSfW installation. If existing DNS Zones are reused, ensure that the DSfW DNS server serving the domain is set as Designated Primary for the zones after deploying the domain controllers. This is applicable for all forward and reverse zones.
