      Tree and Forest in Active Directory

      The Domain is the core unit of logical structure in Active Directory. All objects that share a common directory database and trust relationship with other domain and security policies are known as Domains. Each domain stores information only about the objects that belong to that domain. All security polices and settings, such as administrative rights,

      When a change is made to a domain, the change is replicated across all of the domain controllers in the domain. Some changes, such as those made to the schema, are replicated across all of the domains in the forest. This replication is called multimaster replication. But few changes are practically not possible to perform

      Active Directory Terminology and Concepts

      The Active Directory data store (directory) is the database that holds all directory information such as information on users, computer, groups, other objects, and the objects that users can access. It also includes other network components. The Active Directory data store is stored on the server’s hard disk by means of the Ntds.dit file. The

      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

      Domains and Forests can also share resources available in active directory. These resources are searched by Global Catalog across domains and forests and this search is transparent to user. For example, if you make a search for all of the printers in a forest, this search goes to global catalog server for its query and

      An Overview on Performance Monitoring and Management Performance monitoring is the process of accurately and consistently measuring performance, so that you can identify any potential bottlenecks which may be impairing the way in which Active Directory performs within your environment. A bottleneck can take place on any Windows subsystem or network component, and occurs when

      Understanding Forests and Domains

      A domain is a collection of computers and resources that share a common security database, in this case, the Active Directory database. Computers in the domain also have a common namespace. A namespace is the hierarchical grouping of service and object names that are stored in Active Directory and DNS. Active Directory and DNS namespaces

      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

      Troubleshooting Active Directory Availability

      As an Administrator, ensuring the availability and reliability of the Windows Server Active Directory directory service is extremely important if you are running Active Directory within your environment. Performance problems and poor availability leads to users being unable to perform their tasks or duties within the organization. For instance, when a DNS server fails, it
