How do I...Install and configure a DNS server in Windows Server 2008?

Choosing your Zone Type

When selecting a DNS zone type, you have the following options:
  • Active Directory (AD) Integrated
  • Standard Primary, and
  • Standard Secondary
AD Integrated stores the database information in AD and allows for secure updates to the database file. This option will appear only if AD is configured. If it is configured and you select this option, AD will store and replicate your zone files.

A Standard Primary zone stores the database in a text file. This text file can be shared with other DNS servers that store their information in a text file.

Finally, a Standard Secondary zone simply creates a copy of the existing database from another DNS server. This is primarily used for load balancing.
