Microsoft windows 2000 DNS manual Windows 2000 White Paper

Each Active Directory service object has attributes associated with it that define particular characteristics of the object.

The classes of objects in the Active Directory service database as well as each object’s attributes are defined in the Active Directory service schema. In other words, the schema contains definitions for each class object available in Active Directory service. The following are examples of the Active Directory service class objects:

•User

•Group

•Organizational Unit

•DnsZone

•DnsNode

In DS integrated DNS, each DNS zone becomes an Active Directory service container object (DnsZone). The DnsZone object will contain a DnsNode leaf object for every unique name within that zone. The DnsNode object will have a DnsRecord multi-valued attribute with an instance of a value for every record associated with the object’s name.

In the screen shot above, the object mail.mydomain.microsoft.com may have the A attribute containing the IP address for mail.mydomain.microsoft.com. and the MX attribute containing the mail exchange server information for mail.mydomain.microsoft.com.
