How to List All Domain Controllers with PowerShell

In this post, I will show you how to list all domain controllers with PowerShell.

To list all domain controllers the Get-ADDomainController PowerShell cmdlet is used. The Get-ADDomainController cmdlet can get all domain controllers or list specifics ones with the various search parameters.

Let’s get started!

Example 1: List all domain controllers in the domain

This command will list the name of each domain controller only, no additional info.

Get-ADDomainController -filter * | Select-Object name

Example 2: List all domain controllers (with full details)

If you want more details like the domain name, forest, IP address, etc use this command.

Get-ADDomainController -filter * 

In the above screenshot you can see this command provides a lot of information on each domain controller. You can use the select object command to list only specific details. The next example will demonstrate this.

Example 3: List Domain Controllers in another domain

To list domain controllers from another domain you can use the -server parameter then the fully qualified domain name. This example uses select to display just the Name, Domain, Forest, IP address and site details.

Get-ADDomainController -server arizona.ad.activedirectorypro.com | Select Name, Domain, Forest, IPv4Address, Site

Example 4: List Domain Controllers with Site Information

There is no simple command to list domain controllers from a specific site. So you can list them all and include the site information in the output.

Get-ADDomainController -Filter * | Select hostname, site

In the screenshot above you can see I have two domain controllers in one site and another dc listed in a separate site.

Example 5: Export list of Domain Controllers to csv

To export any of these commands just add export-csv -path to the end.

Get-ADDomainController -filter * | Select-Object name | export-csv -path c:\temp\all-domain-controllers.csv

Example 6: List available domain controller in Current Domain

This will not list all domain controllers but will use the DCLocator mechanism to return a discoverable DC.

Get-ADDomainController -Discover

Why is this important? The DCLocator is a process used by Windows to locate the closest domain controller. It can be useful to verify that client systems are locating and authenticating to the closest DC. To learn more on this see the Microsoft article How Domain Controllers are located in Windows.

All done! Now you know how to get a list of domain controller by using PowerShell.
