When you install the DNS Server role, there are no choices to make—just a couple of clicks, and
you're finished. When you finish the installation, DNS Manager, shown previously, is available
in the Administrative Tools folder and in Server Manager.
Creating DNS Zones
As mentioned, when DNS is installed as part of the Active Directory installation, the DNS zone
that's created is integrated with Active Directory by default and called an Active Directory-
integrated zone . An Active Directory-integrated zone is not a new zone type; it's a primary or
stub zone with the DNS database stored in an Active Directory partition rather than a text file.
Because Active-Directory zones are replicated to other domain controllers automatically, only
primary and stub zones can be Active Directory integrated. Therefore, a secondary zone can't be
an Active Directory-integrated zone, but a file-based secondary zone can be created from an
Active Directory-integrated zone, as when two DNS servers are in different forests.
If DNS is installed on a domain controller that's part of an existing domain, zone informa-
tion is copied to the new domain controller by default when Active Directory replication occurs.
No action is necessary on the administrator's part to create zones; they are replicated from other
DCs in the domain.
Although DNS zones are created automatically during Active Directory installation, you
might need to create a zone manually in the following situations:
• When you don't install DNS at the time you install Active Directory
• When you install DNS on a server that's not a domain controller
• When you create a stub zone
• When you create a secondary zone for a primary zone that's not Active Directory integrated
• When you create a primary or secondary zone for an Internet domain
If you create a zone manually, you can choose whether it should be Active Directory inte-
grated. A zone that isn't Active Directory integrated is referred to as a standard zone . Figure 9-6
shows the zone type options when you're creating a new zone.

Selecting the zone type
Active Directory-Integrated Zones The “Store the zone in Active Directory” check
box in Figure 9-6 means you want the zone to be stored in an Active Directory partition. The
server where you're creating the new zone must be a standard domain controller (as opposed to
