The Active Directory database is logically separated into directory partitions: Schema partition Configuration partition Domain partition Application partition Each partition is a unit of replication and each partition has its own replication topology. Replication occurs between directory partition replicas. Minimum two directory partitions are common among all domain controllers in the same forest: the schema …
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. …
The initial Windows NT versions were designed as single master network environments. The primary domain controller (PDC) was responsible for managing the domain database’s master copy. The PDC was therefore responsible for replicating any changes to the backup domain controllers (BDCs). In these environments, any changes had to be performed on the PDC, which then …
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functional levels provide a means of enabling additional domain and forest-wide Active Directory features, remove outdated backward compatibility in an environment, and improve Active Directory performance and security.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 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 …
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 …
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 …
On Overview on Group Policy Before you can consider to even begin planning a Group Policy implementation in your organization, you have to understand a few important aspects of Group Policy. Microsoft initially introduced group policies in Windows NT to assist administrators in managing the desktop configuration settings of users and computers. Windows Server 2000 …
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, …
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 …
