Have you been searching for an article that explains the Active Directory Users and Computers (ADUC) tool? You’ve just found it, as this is a deep dive into this topic!
In the first section of this article, I’ll introduce you to ADUC. Then, in section two, you’ll learn how ADUC works, followed by its features in section three.
Not only that, but I also covered the benefits and limitations of ADUC in section four. I also have a section that shows you how to install ADUC in Windows 10 and Windows 11.
Finally, you can read my answers to commonly asked questions about ADUC in the FAQ section.
Overview of Active Directory Users And Computers (ADUC)
SysAdmins use Active Directory Users and Computers to manage users, groups, organizational units, and all other Active Directory objects. If you open ADUC in a fresh installation of Active Directory, you’ll find the nodes shown in the screenshot below.
As you can see from the screenshot above, you can manage Built-in groups, Domain-joined computers, and Domain Controllers. In addition to those, you can also manage ForeignSecurityPrincipals, Managed Service Accounts, and Users.
That is not all. You can also use Active Directory Users and Computers to create AD users, Groups, and Organizational Units.
There is more to this versatile tool, and in the subsequent sections, you’ll have an in-depth view of ADUC. In addition to that, you’ll also learn all the admin tasks you can perform with it.
How Active Directory Users And Computers (ADUC) Works
Active Directory is a multi-master database that stores objects across multiple Domain Controllers in a Domain. By “multi-master,” I mean that an Active Directory object (like a user) is saved on multiple Domain Controllers.
So, where does ADUC come in?
While Active Directory stores and manages objects in its database, ADUC is your interface to add and/or edit these objects. So, when you create or modify an object in ADUC, you’re making the change in the Domain Controller you’re connected to.
Then, the Domain Controller replicates the changes to other Domain Controllers in Active Directory. Generally, due to its “multi-master” model, multiple SysAdmins can connect to different Domain Controllers and modify the same object.
When this happens, Active Directory manages the replication and conflict resolution to maintain the integrity of objects.
It is important to mention that even though AD is a multi-master database, some objects have to be modified using a single-master model.
“Single-master” means that, for such objects, only one Domain Controller MUST modify the single-master object; then replicate the changes to other Domain Controllers.
For the purpose of ADUC, all you need to understand is that when you make changes to Active Directory (AD) via Active Directory Users and Computers, AD manages the replications. In addition to that, it also manages conflict resolution as well.
Features Of Active Directory Users And Computers (ADUC)
To help you make the best of ADUC, this section outlines and discusses its core features.
Delegate Control To Junior Admins Via ADUC
One of the essential features of Active Directory Users and Computers is that you can use it to delegate control to other admins. To reduce risk to your AD forest, Microsoft recommends the “lease access” model.
That is, only grants the access people need to perform specific functions. So, if you need a team member to perform more tasks in AD, you can use the ADUC delegation tool to grant user-specific access.
To delete access in Active Directory Users and Computers:
- Open ADUC, then, right-click your domain name and select Delegate Contol.
- When the Delegate Contol wizard opens, enter the user name of the person you want to delegate control to and click Next.
- Finally, select the tasks you want to delegate.
Active Directory Users And Computers Has A Search Functionality
As I hinted earlier, you can access AD objects via the ADUC nodes. However, if you manage an Active Directory domain with thousands of objects, it may be more efficient to search for objects.
Fortunately, ADUC has search functionality. To access this feature, right-click your AD Domain name and select Find.
Alternatively, click the Action menu and select Find.
Change Domain, Domain Controllers, Or Change Domain Functional Level
If you open Active Directory Users and Computers, it automatically connects to a default domain. In addition to that, ADUC also connects to a default Domain Controller.
However, if you want to connect to another domain and/or Domain Controller, you can use ADUC to do so. To connect to another Domain or Domain Controller right-click your current AD Domain, then select the option you require.
Apart from changing the Domain or Domain Controller, you can also use ADUC to raise the Domain Functional Level of your AD Domain.
To access this feature, click the Action menu. Then, click Raise domain functional level.
View Domain Controllers With The RID, PDC, And Infrastructure Masters Roles
ADUC also offers you the feature to view and change the Domain Controller that currently holds three out of the five Flexible Single Master Operations (FSMO) roles.
To view the current holders of these three roles click the Action menu; then select Operations Masters.
Active Directory Users and Computers will then display a smaller window with three tabs – RID, PDC, and Infrastructure. If you wish to move an FSMO role to another DC, first log in to the DC.
Then, open the Operations Masters window from ADUC and select Change.
Create Users, Computers, Groups, And Other AD Objects With ADUC
The commonest task SysAdmins perform in Active Directory Users and Computers is to create objects. To create common AD objects like Users, Groups, and Printers with ADUC, point to the Actions menu.
Then, point to New and select the object you want to create.
Active Directory Users And Computers Has An Advanced Feature
In the overview section of this guide, I showed you the view of ADUC for a new AD installation. Here it is…
In addition to the nodes shown in the default view, you can enable the Advanced View to give you access to nodes you can use to perform advanced ADUC tasks.
To enable the Advanced Features of Active Directory Users and Computers, click the View menu. Then, select Advanced Functions.
ADUC will now display additional nodes. In the screenshot below, I have labeled the nodes added when you enabled Advanced Features in Active Directory Users and Computers.
Benefits (Pros) And Limitations (Cons) Of Active Directory Users And Computers (ADUC)
Every piece of technology has its strengths and weaknesses and ADUC is no exception. In this section, I’ll highlight the main pros and cons of Active Directory Users and Computers.
Benefits (Pros) Of Active Directory Users And Computers (ADUC)
From the previous sections of this article, you would have deduced the various advantages of using ADUC. However, in this sub-section, I have highlighted some of the core benefits of this tool.
- ADUC is easy to use. This AD tool has a simple interface that gives you quick access to all its nodes and the ability to manage Active Directory
- You can install ADUC on Windows 10 or Windows 11. Even though you can access ADUC by logging in directly to a Domain Controller, this is not the best practice.
Microsoft’s best practice is to install ADUC on your Windows 10 or 11 computer. The great news is that you can install this tool by enabling RSAT for AD on your Windows 10 or Windows 11 computer.
- Active Directory Users and Computers have Filter Options. You can use Active Directory Users and Computers with its default view.
However, if you work with specific nodes, you can use the Filter Options to select the nodes you want to display.
To open the Filter Options, click the View menu. Then, select Filter Options.
- Active Directory Users and Computers has a shortcut menu. ADUC has a short-cut menu that grants you quick access to perform tasks.
In the screenshot below, I have highlighted ADUC’s shortcut menu. The shortcuts available in the menu change depending on the object you selected in the left pane of ADUC.
Limitations (Cons) Of Active Directory Users And Computers (ADUC)
Believe it or not, ADUC has some limitations. The purpose of this sub-section is to highlight these limitations.
In addition to that, I will also point you to the alternative tools you can use to perform the tasks you cannot perform with ADUC.
- You cannot create Dynamic Access Contol with ADUC. One of the limitations of ADUC is that it does not include the option to create some advanced policies and access controls.
To create these advanced tools like Dynamic Access Contol and Authentication policies, use Active Directory Administrative Center.
You can open Active Directory Administrative Center in a Domain Controller from the Tools menu of Server Manager.
- ADUC does not offer the option to enable Active Directory Recycle Bin. If you need to enable AD Recycle Bin, do it via Active Directory Administrative Center.
To enable Recycle Bin via Active Directory Administrative Center, right-click your domain name. Then, select Enable Recycle Bin.
- You cannot raise Forest’s functional level with ADUC. Active Directory Users and Computers have the option to raise Domain functional level.
However, if you want to raise the functional level, you must perform the task from either the Active Directory Administrative Center or Active Directory Domains and Trusts.
- ADUC does not have the option to manage AD Trusts or Sites. Apart from all the objects you can manage via ADUC, AD has other features that you need to manage.
For example, you need to manage AD Sites and inter-domain trusts. To manage AD Trusts, use Active Directory Domains and Trusts.
On the other hand, if you need to manage AD Sites, you need to use Active Directory Sites and Services.
