Replication Service: The Active Directory replication service transfers information about all objects across the network to different active directory domain controllers to ensure they are all in sync with the most up-to-date information. Active Directory Security Groups An everyday use case of Active Directory is to authenticate and authorize users on the network. Active Directory has many security groups: Universal: Universal groups contain accounts from any domain in the same Active Directory Forest or global groups from any domain in the same forest.

Global: Global groups contain accounts from the same domain and other global groups from the same domain. Domain Local: Domain local groups contain accounts from any domain or any trusted domain, global groups from any domain or any trusted domain, universal groups from any domain in the same forest, other domain local groups from the same domain, and other global or universal groups from other forests. Prerequisites There are multiple ways to find out which Active Directory groups a user is a part of.

The main reason is convenience. Active Directory enables users to log on to and manage a variety of resources from one location. Login credentials are unified so that it is easier to manage multiple devices without having to enter account details to access each individual machine.

Then do the following:. One of the first things you need to do when using Active Directory is to set up a domain controller. A domain controller is a central computer that will respond to authentication requests and authenticate other computers throughout the network.

The domain controller stores the login credentials of all other computers and printers. All other computers connect to the domain controller so that the user can authenticate every device from one location.

The process of setting up a domain controller is relatively simple. Now follow these instructions:. The procedures for adding a domain controller to an existing domain in Active Directory are the same, no matter which operating system you have. However, these instructions were organized during an exercise on Windows Server It is always a good idea to have at least two domain controllers in your AD domain just in case one goes down.

The second Domain Controller is a separate computer from the one identified for your first Domain Controller.

That second computer needs to be set up with Windows Server Get it fully patched and assign it an IP address before starting the AD setup on that machine. Then follow these steps:. Go back to your original domain controller computer and open Active Directory Users and Computers and you will see that your new DC is listed there in the Domain Controllers folder.

Users and computers are the two most basic objects that you will need to manage when using Active Directory. You can install ADUC by following the instructions listed below:. Like all forms of infrastructure, Active Directory needs to be monitored to stay protected. Monitoring the directory service is essential for preventing cyber-attacks and delivering the best end-user experience to your users.

Forest and trees are two terms you will hear a lot when delving into Active Directory. These terms refer to the logical structure of Active Directory. Briefly, a tree is an entity with a single domain or group of objects that is followed by child domains. A forest is a group of domains put together.

When multiple trees are grouped together they become a forest. Trees in the forest connect to each other through a trust relationship, which enables different domains to share information. All domains will trust each other automatically so you can access them with the same account info you used on the root domain. Each forest uses one unified database. Logically, the forest sits at the highest level of the hierarchy and the tree is located at the bottom.

One of the challenges that network administrators have when working with Active Directory is managing forests and keeping the directory secure.

For example, a network administrator will be tasked with choosing between a single forest design or multi-forest design. The single-forest design is simple, low-cost and easy to manage with only one forest comprising the entire network. In contrast, a multi-forest design divides the network into different forests which is good for security but makes administration more complicated.

As mentioned above, trusts are used to facilitate communication between domains. Trusts enable authentication and access to resources between two entities. Trusts can be one-way or two-way in nature. Within a trust, the two domains are divided into a trusting domain and a trusted domain.

In a one-way trust, the trusting domain accesses the authentication details of the trusted domain so that the user can access resources from the other domain. All domains within a forest trust each other automatically , but you can also set up trusts between domains in different forests to transfer information.

You can create trusts through the New Trusts Wizard. The New Trust Wizard is a configuration wizard that allows you to create new trust relationships. Here you can view the Domain Name , Trust Type , and Transitive status of existing trusts and select the type of trust you want to create. Generating reports on Active Directory is essential for optimizing performance and staying in accordance with regulatory compliance.

The tool has been created to increase visibility into how directory credentials are used and managed. For example, you can view accounts with insecure configurations and credential abuse that could indicate a cyber attack. Using a third-party tool like SolarWinds Access Rights Manager is beneficial because it provides you with information and features that would be much more difficult or impossible to access through Active Directory directly.

As well as generating reports you can automatically delete inactive or expired accounts that cybercriminals target. There is also a day free trial version that you can download. See also: Access Rights Management. The easiest way to find account lockouts in Active Directory is to use the Event Viewer, which is built into Windows.

Active Directory generates Windows Events messages for each of its actions, so your first task is to track down the right event log. The Event Report will show you the user that was locked out, the computer that the event occurred on, and the source, or reason for the lockout. Domains: A domain represents a group of objects such as users, groups, and devices, which share the same AD database.

You can think of a domain as a branch in a tree. A domain has the same structure as standard domains and sub-domains, e. Trees: A tree is one or more domains grouped together in a logical hierarchy. Forest: A forest is the highest level of organization within AD and contains a group of trees. The trees in a forest can also trust each other, and will also share directory schemas, catalogs, application information, and domain configurations.

Organizational Units: An OU is used to organize users, groups, computers, and other organizational units. Some of those services have been listed below:. It provides only a subset of the AD DS features, which makes it more versatile in terms of where it can be run.

For example, it can be run as a stand-alone directory service without needing to be integrated with a full implementation of Active Directory. Certificate Services: You can create, manage and share encryption certificates, which allow users to exchange information securely over the internet. Rights Management Services: AD RMS is a set of tools that assists with the management of security technologies that will help organizations keep their data secure.

Such technologies include encryption, certificates, and authentication, and cover a range of applications and content types, such as emails and Word documents. A comprehensive step-by-step guide to setting up Active Directory on Windows Server is beyond the scope of this article.
