What Are DNS Zones?

ANS : A zone starts as a storage database for a single DNS domain name. If other domains are added below the domain used to create the zone, these domains can either be part of the same zone or belong to another zone. Once a subdomain is added, it can then either be:

●    Managed and included as part of the original zone records, or
●    Delegated away to another zone created to support the subdomain

26. What is Integration of DNS and Active Directory ?

What is Integration of DNS and Active Directory

The integration of DNS and Active Directory is essential because a client computer in a Windows 2000 network must be able to locate a domain controller so that users can log on to a domain or use the services that Active Directory provides. Clients locate domain controllers and services by using A resource records and SRV records. The A resource record contains the FQDN and IP address for the domain controller. The SRV record contains the FQDN of the domain controller and the name of the service that the domain controller provides.
