The Active Directory groups are a collection of Active Directory objects. The group can include users, computers, other groups, and other AD objects. The administrator manages the group as a single object.

Ans: Special identity groups are groups whose membership lists you cannot manually modify or view.

There are three types of groups in Active Directory: Universal, Global, and Domain Local. There are two main functions of groups in Active Directory: Gathering together objects for ease of administration.

Mail-enabled universal distribution groups (also called distribution list groups) can be used only to distribute messages. Mail-enabled universal security groups (also called security groups) can be used to distribute messages and to grant access permissions to resources.

Distribution groups Distribution groups are used for distributing messages to group members. Distribution groups are used with e-mail applications, such as Microsoft Exchange. Distribution groups are not security enabled, and therefore cannot be used to assign permissions to Windows resources.

universal group is a security or distribution group that contains users, groups, and computers from any domain in its forest as members. You can give universal security groups rights and permissions on resources in any domain in the forest.

Default groups, such as the Domain Admins group, are security groups that are created automatically when you create an Active Directory domain. You can use these predefined groups to help control access to shared resources and to delegate specific domain-wide administrative roles.

To create a security group, do the following:

1. Within Active Directory, it’s simple to choose New and click Group.
2. There you can name the new group, choose Universal for Group Scope, and Security for Group Type.
3. Once the group is created, you can find the Members tab within Properties, and click Add.

Universal groups Universal security groups are most often used to assign permissions to related resources in multiple domains. Members from any domain may be added. Also, you can use a universal group to assign permissions for access to resources in any domain.

Active Directory Nested Groups Best Practices.

• Add user and computer accounts to a global group.
• Add the global group to a universal group.
• Add the universal group to a domain local group.
• Apply Active Directory security group permissions for the domain local group to a resource.

Universal groups can not be members or global groups. Only global groups can be members of other global groups. universal groups can be members of other universal groups or local domain groups.

The difference between domain local and global groups is that user accounts, global groups, and universal groups from any domain can be added to a domain local group. Because of its limited scope, however, members can only be assigned permissions within the domain in which this group is created.

Domain Local Group is a type of group in a Microsoft Windows Server-based network. Windows Server uses groups to organize users or computer objects for administrative purposes. Domain local groups are used to provide users with access to network resources and to assign permissions to control access to these resources.

Distribution groups are used for sending email notifications to a group of people. Security groups are used for granting access to resources such as SharePoint sites. Mail-enabled security groups are used for granting access to resources such as SharePoint, and emailing notifications to those users.

Group Policy provides centralized management and configuration of operating systems, applications, and users’ settings in an Active Directory environment. A set of Group Policy configurations is called a Group Policy Object (GPO).

Group Policy Objects, or GPOs, are assigned by linking them to containers (sites, domains, or Organizational Units (OUs)) in Active Directory (AD). Then, they are applied to computers and users in those containers. User GPO processing can be modified by using loopback processing mode, as shown in the table below.

The four unique levels of hierarchy for Group Policy processing are called Local, Site, Domain, and OU. Let’s spend a few minutes going through each one so that you can understand how they are different, and also how they fit together.

This can be useful for locking down computers, restricting access to specific folders, control panel applets, and applications. It can also be used to change a variety of Windows settings, including ones that can’t be changed from the control panel or require registry tweaks to change.

Start → Administrative tools → Group policy management console. Navigate to the desired OU, to which you want to link a GPO. Right click on this OU and select “Link an existing GPO” . In the “Select GPO” dialog under Group Policy Objects, select the GPO you want to link and click OK.

Group Policy is a feature of the Microsoft Windows NT family of operating systems (including Windows 7, Windows 8.1, Windows 10, and Windows Server 2003+) that controls the working environment of user accounts and computer accounts. A set of Group Policy configurations is called a Group Policy Object (GPO).

Group Policy is applied to the user or computer, based upon where the user or computer object is located in the Active Directory. However, in some cases, users may need policy applied to them, based upon the location of the computer object, not the location of the user object.

Group Policy provides a method of centralizing configuration settings and management of operating systems, computer settings and user settings in a Microsoft IT environment. Group Policy is a twofold idea: Local Group Policy on individual workstations and Group Policy in Active Directory.

Open Local Group Policy Editor by using the Run window (all Windows versions) Press Win + R on the keyboard to open the Run window. In the Open field type “gpedit. msc” and press Enter on the keyboard or click OK.

Click on ‘Group Policy Objects’ container to view all the GPOs available in the domain. For each GPO, you will also be able to see the status of the ‘user configuration settings’ and also the ‘computer configuration settings’. From the list of all available GPOs, click on the required GPO.

To start GPMC, do the following: On the Start screen, click the Apps arrow. On the Apps screen, type gpmc. msc, and then click OK or press ENTER.

Installing the Group Policy Management Console (GPMC)

1. Go to Start > Control Panel, and select Turn Windows features on and off under Programs.
2. In the Add Roles and Feature Wizard window that opens, select Features.
3. Check Group Policy Management, and click Next.
4. Click Install.

The Group Policy Management Console (GPMC) is a central resource for managing groups of Group Policy Objects (GPOs). Group Policy Objects set controls for aspects of easier administration. They have to be distributed throughout a system to effectively work to help administrators manage users and computers.

Windows 10 Version 1809 and Higher

1. Right-click the Start button and choose “Settings” > “Apps” > “Manage optional features” > “Add feature“.
2. Select “RSAT: Group Policy Management Tools“.
3. Select “Install“, then wait while Windows installs the feature.
