A prerequisite for every PowerShell Active Directory (AD) task is to install the Active Directory module. This popular module allows administrators to query and make changes to Active Directory with PowerShell.
In this blog post, we're going to dive into how to install the PowerShell Active Directory module on Windows 10. We'll then cover how to connect to AD with PowerShell and go into the various ways you can authenticate to AD.
Install RSAT (Remote Server Administration Tools)
Before we begin, you should first be aware of the RSAT package. If you are using a workstation variant of Windows then you will need to install the Remote Server Administration Tools (RSAT) package. If you are using a Server variant of Windows, then you will already have RSAT available.
If you don't have RSAT you'll get the annoying 'the term Get-AD* is not recognized as the name of a cmdlet, function, script file, or operable program' type messages when you attempt to run the commands we'll be covering.
RSAT for Pre 1809 Windows 10
If you're on Windows 10 pre-build 1809, download an RSAT package from Microsoft. The install is simple and straightforward.

Once you have installed RSAT, ensure the Active Directory Module for Windows PowerShell is enabled in Windows Features. By default, it should be already.
RSAT for post-1809 Windows 10
In versions of Windows from 1809 onwards the RSAT capabilities are available as optional features. There's no need to download an external packages.
To install the ActiveDirectory module on Windows 10 post-1809, use the
Add-WindowsCapability cmdlet. This enables the Rsat.ActiveDirectory.DS-LDS.Tools optional feature as shown below.
PS51> Add-WindowsCapability -Online -Name Rsat.ActiveDirectory.DS-LDS.Tools~~~~0.0.1.0
The above syntax was tested on Windows 10 Build 1903 and on Windows 7.
RSAT for Windows Server 2008R2 and Later
On Windows Server, use the PowerShell ServerManager module to enable the RSAT-AD-PowerShell feature in PowerShell.
PS51> Import-Module ServerManager PS51> Install-WindowsFeature -Name RSAT-AD-PowerShell
How to PowerShell Load the AD Module
Although it's likely PowerShell will auto-import the module when installed. But if you'd like to ensure it loads properly, you can also the
To use PowerShell to import the Active Directory module, run
Install-Module ActiveDirectory. If the module is installed in the right place, you will receive no errors.
Connecting and Authenticating
Once the ActiveDirectory module is set up, you can then use the Active Directory PowerShell cmdlets.
Although the cmdlets interact with different parts of AD, nearly all of them have common parameters. Two of those parameters are
Connecting to a Specific Active Directory Domain Controller
By default, the AD cmdlets will find a domain controller for you. However, if you need to connect to a different domain controller, you can use the
Server parameter isn't mandatory. PowerShell will attempt to find a domain controller to connect to by default. The domain controller is determined by trying the following in the listed order:
- Use the
Serverproperty of objects passed in on the pipeline.
- Use the server associated with the AD PowerShell provider drive, if in use.
- Use the domain of the client computer.
You can connect to a specific domain controller by providing a value for the
Server parameter. You can specify several different ADDS objects in different formats such as:
- A domain name specified as a FQDN or NETBIOS name such as domain.local or DOMAIN
- A domain controller specified as a FQDN or NETBIOS name such as server.domain.local or SERVER
- A fully-qualified domain controller and port such as server.domain.local:3268
Connecting to Active Directory with Alternate Credentials
By default, the Active Directory PowerShell cmdlets will use a two-step process for determining the user account to connect to AD with.
- Use the credentials associated with the PowerShell AD provider drive, if the command is run from there.
- Use the credentials of the logged-on user.
You can also specify alternate credentials using the
Credential parameter allows you to pass in a PSCredential object. If you provide a username, you will be prompted for a password and these credentials will be used.
You can see an example below of using the
Get-AdUser cmdlet using an alternate credential.
You also have two possible authentication types available, controlled by the
AuthType parameter. These types are Negotiate (the default) and Basic. Basic authentication is only possible over an SSL connection.
Setting up the ActiveDirectory PowerShell module is a straightforward and common process. Using the instructions provided in this article, you should be well on your way to automating all the Active Directory things!
