Dns forward zone not updating

Rated 3.87/5 based on 743 customer reviews

Typically, a backup of the primary zone is made to a secondary zone.

A secondary zone is read-only and cannot be edited.

Leaving this to the default setting will speed up DNS queries. This practice also provides a better documented DNS system over time, and keeps PTR records from getting improperly configured with Alias names.

Instead create a sub-zone and create the Host records there and create an Alias (CNAME) record in the appropriate zone.

DNS is an important prerequisite of Active Directory.

Stub zones were introduced with Windows Server 2003 and contain only the resource records that are required to identify the authoritative DNS servers for the master zone.It is the primary name resolution service for Active Directory.The DNS service provides domain name services and the DNS database can be integrated with Active Directory or stored in an external database. A DNS zone is a contiguous part of the DNS domain name space, meaning it is a portion of a namespace and not a domain.This makes sure that the information is replicated to all the DNS servers in the domain or the forest.It is recommended you set this to replicate to the Forest. Stub Zones can automatically be replicated to all DNS servers when AD integrated Zones are used and work similar to DNS forwards.
