Creating an Active Directory Domain

The Windows 2000 Cluster service runs in the context of a Windows-based domain
security policy, typically created specifically for the Cluster service to use. For the
Cluster service to form a cluster on a given node, the service must first authenticate
itself using the credentials of this policy. A domain controller must be available for
the domain that issued the policy for authentication to occur. If the Cluster service
does not have access to a domain controller, it cannot form a cluster.

Note:

For Active Directory to function properly, DNS servers must provide support
for Service Location (SRV) resource records described in RFC 2052,

A DNS

RR for specifying the location of services (DNS SRV)

. SRV resource records

map the name of a service to the name of a server offering that service.
Active Directory clients and domain controllers use SRV records to
determine the IP addresses of domain controllers. Although not a technical
requirement of Active Directory, it is highly recommended that DNS servers
provide support for DNS dynamic updates described in RFC 2136,

Observations on the use of Components of the Class A Address Space
within the Internet

The Windows 2000 DNS service provides support for both SRV records and
dynamic updates. If a non-Windows 2000 DNS server is being used, verify that it at
least supports the SRV resource record. If not, it must be upgraded to a version
that does support the use of the SRV resource record. A DNS server that supports
SRV records but does not support dynamic update must be updated with the
contents of the Netlogon.dns file created by the Active Directory Installation wizard
while promoting a Windows 2000 Server to a domain controller.

By default, the Active Directory Installation wizard attempts to locate an authoritative
DNS server for the domain being configured from its list of configured DNS servers
that will accept a dynamic update of an SRV resource record. If found, all the
appropriate records for the domain controller are automatically registered with the
DNS server after the domain controller is restarted.

If a DNS server that can accept dynamic updates is not found, either because the
DNS server does not support dynamic updates or because dynamic updates are
