Specify Other DNS Servers as Authoritative for a Zone

Applies To: Windows Server 2008, Windows Server 2008 R2

Use this procedure to add secondary servers for your existing zones to the name server (NS) record to make them authoritative for the zone. Typically, it may be necessary to perform this procedure at the primary zone only when you add Domain Name System (DNS) servers to act as secondary servers. You can also perform this procedure to specify that these servers are known to be authoritative when they answer queries for zone data. DNS servers automatically add and perform initial configuration of the name server NS resource record for each new primary zone that is added to the server.

Membership in the Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at
