Microsoft Windows Active Directory includes both a physical component as well as a logical one. The physical component consists of a database file stored on domain controllers (DC) and the logical aspect of Active Directory consists of the various objects such as domains, forests, organizational units, etc.
What are the components of Active Directory?
The components making up Active Directory can be broken down into logical and physical structures. Logical components in Active Directory allow you to organize resources so that their layout in the directory reflects the logical structure of your company.
What is the difference between physical and logical structure of Active Directory?
In Active Directory, the logical structure is separate from the physical structure. You use the logical structure to organize your network resources, and you use the physical structure to configure and manage your network traffic. The physical structure of Active Directory is composed of sites and domain controllers.

What is the logical structure of Active Directory?
Active Directory forest A forest is a collection of one or more Active Directory domains that share a common logical structure, directory schema (class and attribute definitions), directory configuration (site and replication information), and global catalog (forest-wide search capabilities).
What are the five components of Active Directory?
The key components include domain, tree, forest, organizational unit, and site. As you read through each structural component description, consider that domains, trees, forest, and sites are not only integral with Active Directory but also integral with DNS.
What are logical components?
A logical component is an administrative entity which assigns logical systems, in the entire system landscape and across projects, to the following: ● a main instance of a product with a product version, e.g. the main instance CRM Server of the product SAP CRM with the product version 4.0.

What are the logical parts of Active Directory?
The logical parts of Active Directory include forests, trees, domains, OUs and global catalogs.
What is a tree in Active Directory?
Tree – a tree is a collection of Active Directory domains that share a contiguous namespace. In this configuration, domains fall into a parent-child relationship, which the child domain taking on the name of the parent.
What is a domain in Windows 2000?
Domain – a domain in Windows 2000 is very similar to a domain is Windows NT. It is still a logical group of users and computers that share the characteristics of centralized security and administration. A domain is still a boundary for security – this means that an administrator of a domain is an administrator for only that domain, and no others, ...
Is a domain a boundary?
A domain is still a boundary for security – this means that an administrator of a domain is an administrator for only that domain, and no others, by default. A domain is also a boundary for replication – all domain controllers that are part of the same domain must replicate with one another.
Can you trust a domain in NT4?
Much like NT 4, trust relationships can exist that allow users from one domain to access resources in another. Domains in the same forest automatically have trust relationships configured, but you should also note that you could create trust relationships to external domains (including NT 4-based domains) if necessary.
What is AD DS?
Designing your logical structure for Active Directory Domain Services (AD DS) involves defining the relationships between the containers in your directory. These relationships might be based on administrative requirements, such as delegation of authority, or they might be defined by operational requirements, such as the need to control replication.
What is a forest in a domain?
A forest is a collection of one or more Active Directory domains that share a common logical structure, directory schema (class and attribute definitions), directory configuration (site and replication information), and global catalog (forest-wide search capabilities). Domains in the same forest are automatically linked with two-way, transitive trust relationships.
What is domain controller?
Domains allow user identities to be created once and referenced on any computer joined to the forest in which the domain is located. Domain controllers that make up a domain are used to store user accounts and user credentials (such as passwords or certificates) securely. Authentication.
Why is the logical model called the logical model?
This is called the logical model because it is independent of the physical aspects of the deployment, such as the number of domain controllers required within each domain and network topology.
How do OUs work?
OUs can be used to form a hierarchy of containers within a domain. OUs are used to group objects for administrative purposes such as the application of Group Policy or delegation of authority. Control (over an OU and the objects within it) is determined by the access control lists (ACLs) on the OU and on the objects in the OU. To facilitate the management of large numbers of objects, AD DS supports the concept of delegation of authority. By means of delegation, owners can transfer full or limited administrative control over objects to other users or groups. Delegation is important because it helps to distribute the management of large numbers of objects across a number of people who are trusted to perform management tasks.
What is the logical structure of an Active Directory site?
In Active Directory, the logical structure is separate from the physical structure. You use the logical structure to organize your network resources , and you use the physical structure to configure and manage your network traffic. The physical structure of Active Directory is composed of sites and domain controllers. We will learn more about these later on. The image below shows sites as part of the physical structure of the network, and domains as part of the logical structure. It is important to note that there is no relationship between sites and domains.
What are the features of Active Directory?
One of the most important features is multi-master replication. It has several advantages.
Is there a relationship between sites and domains?
It is important to note that there is no relationship between sites and domains. The physical structure (sites) and logical structure (domains) of Active Directory are independent of each other with the following consequences. No required relationship between the physical structure of the network and the domain structure of the network.
Is there a connection between domain and site?
Active Directory allows multiple domains in a single site in addition to multiple sites in a single domain. There is no necessary connection between site and domain namespace. Each domain controller belongs to a specific site.
What is a domain in a directory?
Domain, one area of your active directory network, within that area you can shares resources ( File Server, Print Server, email server and etc) Parent Domain, First installation of your AD, you call it first forest and first domain (1Server as an AD).
What is a domain controller?
A domain controller is a server that stores a write copy of Active Directory. They maintain the Active Directory data store. Certain master roles can be assigned to domain controllers within a domain and forest. Domain controllers that are assigned special master roles are called Operations Masters. These domain controllers host a master copy of particular data in Active Directory. They also copy data to the remainder of the domain controllers. There are five different types of master roles that can be defined for domain controllers. Two types of master roles, forest-wide master roles, are assigned to one domain controller in a forest. The other three master roles, domain-wide master roles, are applied to a domain controller in every domain.
What is a domain tree?
Domain Tree, domain that are grouped in hierarchical structures, and how they link together. Organizational Units (OU) is an container, for each object you have inside your Active Directory, you can put user, computer,group, and also you can put another OU inside your current OU.
What is a different domain in the same forest?
Different Domain in same Forest, The same like child domain, installed after first domain deployed in a forest but have different name from the parent (totally different name). For the example as you can see from the picture Woodgrovebank.com is a different domain from contoso.com but it is still within the same forest.
Domain Controllers
A Exam Warning
Master Roles
- Certain changes in Active Directory are only replicated to specific DCs on the network. Operations Masters are DCs that have special roles, keeping a master copy of certain data in Active Directory and copying data to other DCs for backup purposes. Because only one machine in a domain or forest can contain the master copy of this data, they are also referred to as Flexible Single Mast…
Schema
- The schema is a database that is used to define objects and their attributes. Information in the schema is used to control the types of objects (classes) that can be created in Active Directory, and the additional properties (attributes) associated with each. In other words, the schema determines what you can create in Active Directory, and the data that can be used to configure t…
Global Catalog
- As anyone who's tried to search a large database can attest, the more data that's stored in a database, the longer it will take to search. To improve the performance of searching for objects in a domain or forest, the GC is used. The GC server is a DC that stores a copy of all objects in its host domain, and a partial copy of objects in other domains throughout the forest.The partial co…
Replication Service
- The Windows Server 2003 replication service is used to replicate Active Directorybetween DCs, so that each DC has an up-to-date copy of the directory database. Because each DC has an identical copy of the directory, they can operate independently, allowing users to be authenticated and use network resources if one of the DCs fails.This allows Windows Server 2003 DCs to be highly reli…
