The Primary Domain Controller is a server in a Windows network that administers users and their privileges.
A Windows NT server containing the master copy of the account database for a domain. Changes are written to the PDC before being replicated to the Backup Domain Controllers (BDC) in the domain.
A role that can be assigned to the first server installed on a Windows NT 4.0 server or earlier network. The PDC manages the master read/write copy of the directory database for the domain. The PDC authenticates domain logon attempts and updates computer, group, and user accounts in a domain. See also backup domain controller.
The LAN Manager server that maintains the master copy of a domain's user accounts database. The primary domain controller also validates logon requests. In Windows NT Advanced Server domains, the equivalent is the domain controller. See also domain controller.
In an Advanced Server domain, the computer running Advanced Server or Windows NT Server that authenticates domain logons and maintains the master copy of the directory database for a domain. A domain has only one PDC.
The LAN Manager server at which the master copy of a domain's user accounts database is maintained. The primary domain controller also validates logon requests. See also Net Logon service.
A server assigned to administer security for a domain. This server stores the master database of all domain-assigned security data for users and must be updated when changes in security are made. See also Backup Domain Controller (BDC), member server.
In a Windows NT network, the computer that controls the directory database of user accounts, group accounts, and computer accounts on a domain. Also see backup domain controller.
A Windows NT 4.0 and 3.51 domain controller that is the first one created in the domain and contains the primary storehouse for domain data. Within the domain, the primary domain controller periodically replicates its data to the other domain controllers, known as backup domain controllers. See also backup domain controller.
The server at which the master copy of a domain's user accounts database is maintained. The primary domain controller also validates logon requests. A LAN Manager term.
In Windows NT, a database providing a centralized administration site for resources and user accounts. The database allows users to log on to the domain, rather than a specific host machine. A separate account database keeps track of the machines in the domain and allocates the domain's resources to users.
In Windows NT and 2000 networking, this machine is the main machine that responds to security authentication requests, such as logging in, within its domain....
In a Windows NT Server 4.0 or earlier domain, the computer running Windows NT Server that authenticates domain logons and maintains the directory database for a domain. The PDC tracks changes made to accounts of all computers on a domain. It is the only computer to receive these changes directly. A domain has only one PDC. In this version of Windows, one of the domain controllers in each domain is identified as the PDC for compatibility with Windows NT 4.0 and earlier versions of Windows NT. See also: backup domain controller (BDC)
A Primary Domain Controller (PDC) is a server computer in a pre-Windows 2000 NT server Domain. A domain is a concept used in NT server operating systems whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.
