Manipulating DNS Server Configuration

There are close to 50 different settings that can be configured on a Microsoft DNS server. They range from default scavenging and logging settings to settings that customize the DNS server behavior, such as how zone transfers will be sent to secondaries and whether to round-robin multiple A record responses.

The DNS provider is mapped to the root\MicrosoftDNS namespace. A DNS server is represented by an instance of a MicrosoftDNS_Server class, which is derived from the CIM_Service class. Table 27-1 contains all the property methods available in the MicrosoftDNS_Server class.
