AD Step-by-Step Tutorial: Learn the Basics of Configuring AD – Identifying Domain Controllers


For example, Microsoft Windows uses Active Directory information to allow a user to login to their computer and provide access to the security rights assigned in Active Directory. Windows is accessing the directory and then providing rights based on what it finds. If a user account is disabled in Active Directory, the directory itself is just setting a flag which Windows uses to disallow a user from logging in. We mentioned in the introduction that administrators use Active Directory to deploy software this is an incomplete description.

Administrators can set policies and information that a certain software application should be deployed to a certain user AD itself does not deploy the software, but a Windows service reads the information from Active Directory and then installs the software.

Introduced in server and further enhanced for windows server , provides a single reference, called a directory service, to all the objects in a network, including users, groups, computers, printers, policies and permissions.

Active Directory uses a single Jet database which a variety of services and applications can use to access and store a variety of information. Active Directory is used by system administrators to store information about users, assign security policies, and deploy software. AD is used in many different types and size of environments from the very small a dozen users to hundreds of thousands of users in a global environment.

In this tutorial, you will learn the basic structure of Active Directory, gain an understanding of how Active Directory works, learn how to install Active Directory, and learn the components of AD. This tutorial is divided into these sections:.

Why implement Active Directory? Active Directory has a centralized administration mechanism over the entire network. It also provides for redundancy and fault tolerance when two or more domain controllers are deployed within a domain. Active Directory automatically manages the communications between domain controllers to ensure the network remains viable. Users can access all resources on the network for which they are authorized through a single signon. All resources in the network are protected by a robust security mechanism that verifies the identity of users and the authorizations of resources on each access.

History of Active Directory Active Directory was introduced to the world in the mids by Microsoft as a replacement for Windows NT-style user authentication. Windows NT included a flat and non-extensible domain model which did not scale well for large corporations.

Active Directory, on the other hand, was created as a true directory service versus a flat usermanagement service that NT had. Though it was introduced in the s, it did not become a part of the Operating System until Windows Server was released in Since then, Windows Server and Server have been introduced and Active Directory has gone under some expansion. This tutorial is based on Windows Server as it is currently the most widely installed version of the Windows network Operating System NOS , though in the future we will release versions for Windows Server and future Windows releases as it becomes necessary.

Though this tutorial is not focused on Windows Server , much of the basic knowledge and instruction relates to either OS. LDAP is a software protocol for enabling anyone to locate organizations, individuals and other resources such as files and devices in a network, whether on the public Internet or on a corporate intranet.

In a network, a directory tells you where in the network something is located. However, you may not know the domain name. LDAP allows you to search for individuals without knowing where they’re located although additional information will help with the search. An LDAP directory is organized in a simple “tree” hierarchy consisting of the following levels: The root directory the starting place or the source of the tree , which branches out to Countries, each of which branches out to Organizations, which branch out to.

Organizational units divisions, departments and so forth , which branch out to include an entry for Individuals which include people, files and shared resources, such as printers An LDAP directory can be distributed among many servers. Each server can have a replicated version of the total directory that is synchronized periodically.

It is important for every administrator to have an understanding of what LDAP is when searching for information in Active Directory and to be able to create LDAP queries is especially useful when looking for information stored in your Active Directory database. For this reason, many admins go to great lengths to master the LDAP search filter. Active Directory is based loosely on LDAP Lightweight Directory Access Protocol an application protocol for querying and modifying directory services developed at the University of Michigan in the early s.

An LDAP directory tree is a hierarchical structure of organizations, domains, trees, groups, and individual units. Not only does this make the environment look cleaner, but it also allows central system administrators to delegate specific authority over areas to other administrators, team members, and groups.

AD has a very flexible structure, allowing you to build a hierarchy in whatever way you wish one big unit, broken down by geographic location, by department, by astronomical sign, or however you desire. Achieving this flexibility in hierarchical design is a defined structure. The structure of Active Directory starts with forests and domains and goes down to organizational units and individual objects such as a user or computer account.

Basic Active Directory Components It provides the basic building blocks for people to build their own directory. These basic building blocks of Active Directory include domains, domain controllers, trusts, forests, organizational units, groups, sites, replication, and the global catalog. Forests: The collection of every object, its attributes and attribute syntax in the Active Directory.

Domain: A collection of computers that share a common set of policies, a name and a database of their members. Organizational units: Containers in which domains can be grouped. They create a hierarchy for the domain and create the structure of the Active Directory’s company in geographical or organizational terms. Sites: Physical groupings independent of the domain and OU structure. Sites distinguish between locations connected by low- and high-speed connections and are defined by one or more IP subnets.

Understanding Forests At the top of the Active Directory structure is a forest. A forest holds all of the objects, organizational units, domains, and attributes in its hierarchy. Under a forest are one or more trees which hold domains, OUs, objects, and attributes. Forests are not limited in geography or network topology.

A single forest can contain numerous domains, each sharing a common schema. A single network can also be the home of multiple independent forests. However, additional forests may be desired for testing and research purposes outside of the production forest. As illustrated in this image, there are two trees in the forest. You might use a structure like this for organizations with more than one operating company. You could also design a structure with multiple forests, but these are for very specific reasons and not common.

Domains At the heart of the Active Directory structure is the domain. The domain is typically of the Internet naming variety e. Microsoft recommends using as few domains and possible in building your Active Directory structure and to rely on Organizational Units for structure. Domains can contain multiple nested OUs, allowing you to build a pretty robust and specific structure.

Domains serve as containers for security policies and administrative assignments. All objects within a domain are subject to domain-wide Group Policies by default. Likewise, any domain administrator can manage all objects within a domain. Furthermore, each domain has its own unique accounts database. Thus, authentication is on a domain basis. Once a user account is authenticated to a domain, that user account has access to resources within that domain.

In Active Directory, you have multiple Domain Controllers which are equal peers. Replication occurs frequently and on a pull basis instead of a push one. A server requests updates from a fellow domain controller. If information on one DC changes e. Servers not serving as DCs, but in the Active Directory domain, are called member servers. Organizational Units Organizational units are much more flexible and easier overall to manage than domains. OUs grant you nearly infinite flexibility as you can move them, delete them and create new OUs as needed.

However, domains are much more rigid in their existence. Domains can be deleted and new ones created, but this process is more disruptive of an environment than is the case with OUs and should be avoided whenever possible. An Organizational Unit OU is a container which gives a domain hierarchy and structure.

It is used for ease of administration and to create an AD structure in the companys geographic or organizational terms. Organizational Units An OU can contain OUs, allowing for the creating of a multi-level structure, as shown in the image above. There are three primary reasons for creating OUs: Organizational Structure: First, creating OUs allows a company to build a structure in Active Directory which matches their firms geographic or organizational structure.

This permits ease of administration and a clean structure. This, for example, would allow you to apply Active Directory Policies to one OU which are different than another. You could setup policies which install an accounting software application on computers in the Accounting OU. Delegated Administration: The third reason to create OUs is to delegate administrative responsibility. AD Architects can design the structure to allow local administrators certain administrative responsibility for their OU and no other.

This allows for a delegated administration not available in Windows NT networks. Sites By definition, sites are collections of IP subnets that have fast and reliable communication links between all hosts. By using sites, you can control and reduce the amount of traffic that flows over your slower WAN links. This can result in more efficient traffic flow for productivity tasks. It can also keep WAN link costs down for pay-by-the-bit services.

Multiple sites are connected for replication by site links. Typically, sites are used for: Physical Location Determination: Enables clients to find local resources such as printers, shares, or domain controllers.

Replication: You can optimize replication between domain controllers by creating links. By default, Active Directory uses automatic site coverage, though you can purposefully setup sites and resources.

Groups Groups serve two functions in Active Directory: security and distribution. A security group contains accounts which can be used for security access.

For example, a security group could be assigned rights to a particular directory on a file server. A distribution group is used for sending information to users. It cannot be used for security access. There are three group scopes: Global: Global scope security groups contains users only from the domain in which is created. Global security groups can be members of both Universal and Domain Local groups. Universal: Universal scope security groups can contain users, global groups, and universal groups from any domain.

These groups are typically used in a multi-domain environment if access is required across domains. Domain Local: Domain Local scope groups are often created in domains to assign security access to a particular local domain resource. Domain Local scope groups can contain user accounts, universal groups, and global groups from any domain.

Domain Local scope groups can contain domain local groups in the same domain. Trust Relationships Trust Relationships are important in an Active Directory environment so forests and domains can communicate with one another and pass credentials. Within a single forest, trusts are created when a domain is created. By default, domains have an implicit two-way transitive trust created. This means each domain trusts each other for security access and credentials. A user in domain A can access resources permitted to him in domain B while a user in domain B can access resources permitted to her in domain A.

AD allows several different types of trusts to be created, but understanding the twoway transitive trust is the most important to understanding AD. Replication Understanding Active Directory replication Active Directory replication is key to the health and stability of an Active Directory environment.

Without proper and timely replication, a domain will be unable to function effectively. Replication is the process of sending update information for data that has changed in the directory to other domain controllers. It is important to have a firm understanding of replication and how it takes place, both within the domain and in multiple-site environments. There are three main elements or components that are replicated between domain controllers: the domain partition replica, the global catalog and the schema.

The domain partition replica is the Active Directory database of a domain. Each domain controller maintains a duplicate copy of its local domain partition replica. Domain controllers do not maintain copies of replicas from other domains. When an administrator makes a change to the domain, that change is replicated to all domain controllers immediately.

Each forest contains only a single global catalog. By default, the first domain controller installed into a forest is the global catalog server. The global catalog contains a partial replica of every object within each domain of the forest. The global catalog serves as a master index for the forest, which allows for easy and efficient searching for users, computers, resources and other objects.

Any domain controller can be configured to act as a peer global catalog server. You should have at least two global catalog servers per domain and at least one per site. As changes are made to objects within the forest, the global catalog is updated. Once the global catalog is changed on one domain controller, it is replicated to all other domain controllers in the forest. Every domain controller in a forest has a copy of the schema. Just as with changes to the Active Directory database i.

Fortunately, the schema is usually static so there is little replication traffic caused by schema changes. Multi-master replication Within Windows-based Active Directory domains, each domain controller is a peer server.

Each domain controller has equal power and responsibility to support and maintain the Active Directory database. It is this database that is essential to the well-being and existence of the domain itself.

This is such an important task that Microsoft elected to make it possible to deploy multi-redundant systems to support Active Directory by making each domain controller a peer. Whenever a change occurs to any object within an Active Directory domain, that change is replicated automatically to all domain controllers within the domain.

This process is called multi-master replication. Just click on the Next button. Finally, click the Install button. Once the installation process finishes, you will see a notice telling you that additional steps are required. Click on the link that says Promote this server to a domain controller.
