The Active Directory Installation wizard promotes the
computer to the role of domain controller, installs
Active Directory, and can install and configure the DNS
server.
When you start the Active Directory Installation wizard
and choose to create a new domain, the wizard finds the
DNS server that is authoritative for the name of the new
Active Directory domain and then checks whether that
server is going to accept dynamic updates. If the test is
positive, the wizard does not install and configure a
local DNS server.
If the Active Directory Installation wizard cannot find
the DNS server that is authoritative for the name, or if
the server it finds does not support dynamic updates or
is not configured to accept dynamic updates, the Active
Directory Installation wizard asks you whether you want
the wizard to automatically install and configure a local
DNS server. If you answer yes, the wizard automatically
installs and configures the DNS Server service.
During automatic configuration, the Active Directory
Installation wizard adds to the DNS server the forward
lookup zone that will host the locator records and
configures the DNS server to accept dynamic updates. In
some cases, it also primes the root hints with the names
of the root servers. The wizard uses the following
process to determine whether to prime the root hints:
The Active Directory Installation wizard examines the
TCP/IP configuration of the computer and checks whether
the computer is configured to use any DNS servers. If so,
the Active Directory Installation wizard queries for the
root servers. If it finds root DNS servers, it primes the
root hints with the names of the root DNS servers.
If the resolver is not configured to use any DNS servers,
the Active Directory Installation wizard queries for the
root DNS servers specified in the file Cache.dns. By
default, these are the Internet root servers. If it finds
root DNS servers, it primes the root hints with the names
of the root DNS servers. If it does not find any root
servers, it creates a root zone on the DNS server, making
it a root server.
After the Active Directory Installation wizard finishes,
you are prompted to restart the computer. After the
computer restarts, Netlogon attempts to add locator
resource records to the DNS server by sending a dynamic
update request to the authoritative DNS server. Locator
resource records are necessary for other computers to
locate this domain controller.
