## Install Active Directory module for Windows PowerShell
Run PowerShell as administrator and run the command below to install Active Directory module for Windows PowerShell.
```powershell
Add-WindowsFeature RSAT-AD-PowerShell
```
**Important:** You need to install the Active Directory module for Windows PowerShell. Otherwise, it can’t load the Get-ADDomainController cmdlet, and an error appears.
## Get-ADDomainController cmdlet
The [Get-ADDomainController](https://learn.microsoft.com/en-us/powershell/module/activedirectory/get-addomaincontroller) cmdlet is an excellent method to list the Domain Controller in the forest.
```powershell
Get-ADDomainController
```
## Get all Domain Controllers with full details
To get all Domain Controllers, you must run the **Get-ADDomainController** cmdlet, including the **-Filter** string with the wildcard (**\***).
```powershell
Get-ADDomainController -Filter *
```
All the Domain Controllers appear in the PowerShell output.
In our example, we only copied the first section of the output, which is the Domain Controller **DC01-2019**.
