Active Directory clients

The Active Directory client is provided in a single upgrade pack in a Clients folder on the Windows 2000 Server compact disc.

Locating a domain controller

To logon to an Active Directory network, an Active Directory client must first locate an Active Directory domain controller for their domain. To locate a domain controller for a specified domain, an Active Directory client sends a DNS name query to its configured DNS server(s) with the following characteristics:

For example, to logon to the domain microsoft.com, an Active Directory client sends a DNS name query of the type SRV for the name _ldap._tcp.microsoft.com.

The response from the DNS server contains the DNS names of the domain controllers and their IP addresses. From the list of domain controller IP addresses, the client attempts to contact each domain controller to ensure that it is operational. The first domain controller to respond is the domain controller that is used for the logon process.

For more details on this process and details of other types of queries made by Active Directory clients to locate other types of Active Directory servers, see the Windows 2000 Resource Kit
