      Configuring and Troubleshooting Active Directory Replication

      Active Directory is a distributed multimaster replicated database. All domain controllers host a full replica of the domain information for its own domain. Domain controllers in Windows 2000 and Windows Server 2003 environments hold a read/write copy of the Active Directory database. In these environments, changes can be made to the Active Directory database on

    • Active Directory Groups

      Active Directory Groups

      Groups are containers that contain user and computer objects within them as members. When security permissions are set for a group in the Access Control List on a resource, all members of that group receive those permissions. Domain Groups enable centralized administration in a domain. All domain groups are created on a domain controller. In

    • The Global Catalog Server

      The Global Catalog Server

      The Global Catalog (GC) is an important component in Active Directory because it serves as the central information store of the Active Directory objects located in domains and forests. Because the GC maintains a list of the Active Directory objects in domains and forests without actually including all information on the objects and it is

    • Group Policy

      Group Policy

      Group Policy gives users administrative control over people and computers in the user’s network. By using Group Policy, users can define the state of someone’s work environment once, then rely on Windows Server 2003 to continually force the Group Policy settings applied across an entire organization or to specific groups of people and computers. Group

    • Forest and Domain Functional Levels

      Forest and Domain Functional Levels

      Domain and forest functional levels provide a means of enabling additional domain and forest-wide Active Directory features, remove outdated backward compatibility in an environment, and improve Active Directory performance and security. In Windows 2000, the terminology for domain functional levels was domain modes. Forests in Windows 2000 have one mode and domains can have the

    • Active Directory Security

      Active Directory Security

      Active Directory security is determined by the following components: * Security groups: A security group is a made up of a set of users, and is created to assign permissions to access resources, and to assign user rights to group members. Permissions control access to resources, while user rights define what actions users can perform.

    • Replication Topology in Active Directory

      Replication Topology in Active Directory

      Replication Topology is the route by which replication data travels throughout a network. Replication occurs between two domain controllers at a time. Over time, replication synchronizes information in Active Directory for an entire forest of domain controllers. To create a replication topology active directory must determine which domain controller's replicate data with other domain controllers.

    • Understanding Trust Relationships

      Understanding Trust Relationships

      In the Windows NT domain model, domains had to be bound together through trust relationships simply because the SAM databases used in those domains could not be joined. What this meant was that where a domain trusted another Windows NT domain, the members of the domain could access network resources located in the other domain.

    • Creating and Managing Domain Controllers

      Creating and Managing Domain Controllers

      Understanding the Different Server Roles The server roles that exist in a networking environment are standalone servers, member servers and domain controllers. A standalone server is a computer that is not member of a domain, and can be a computer running Windows NT 4, Windows 2000 or Windows Server 2003. A test server is a

    • Physical Structure of Active Directory

      Physical Structure of Active Directory

      In comparison to the logical structure, which performs administrative tasks, the Active Directory physical structure checks when and where logon and replication traffic occurs. The physical structure of Active Directory contains all the physical subnets present in your network like domain controllers and replication between domain controllers. The physical structure of Active Directory: Domain Controllers:
