A Windows domain is a form of a computer network in which all user accounts , computers, printers and other security principals , are registered with a central database located on one or more clusters of central computers known as domain controllers. Authentication takes place on domain controllers. Each person who uses computers within a domain receives a unique user account that can then be assigned access to resources within the domain. Starting with Windows Server , Active Directory is the Windows component in charge of maintaining that central database. Users of a domain are able to use enhanced security for their VPN connection due to the support for a certification authority which is gained when a domain is added to a network, and as a result, smart cards and digital certificates can be used to confirm identities and protect stored information. In a Windows domain, the directory resides on computers that are configured as domain controllers. A domain controller is a Windows or Samba server that manages all security-related aspects between user and domain interactions, centralizing security and administration. A domain controller is generally suitable for networks with more than 10 PCs.
If you use this functionality, you can reduce the requirement for manual administration of zone records, especially for clients that frequently move and use Dynamic Host Configuration Protocol DHCP to obtain an IP address. Windows Server provides support for the dynamic update functionality as described in Request for Comments RFC For DNS servers, the DNS service permits you to enable or to disable the DNS update functionality on a per-zone basis at each server that is configured to load either a standard primary or directory-integrated zone. When you use this functionality, you improve DNS administration by reducing the time that it requires to manually manage zone records. Computers that are running Windows Server can send dynamic updates. Windows Server provides the following features that are related to the DNS dynamic update protocol:. Every Active Directory-integrated zone is replicated among all domain controllers in the Active Directory domain.
