How to get all Domain Controllers in Active Directory Forest with Powershell

Question: I need to configure some applications to use some Domain Controllers . To establish the address - I need to list the Domain Controllers within the Active Directory Forest. Is there a method in Powershell to create a list of Domain Controllers ?

Answer: Powershell has a flexible group of Powershell cmdlets to get information about the Active Directory . Combining Get-ADForest and Get-ADDomainController  will create a recordset 

Here is a sample code snippet. This code will iterate through the Active Directory Forest  and discover the various Domains  :

(Get-ADForest).Domains | % { Get-ADDomainController -Discover -DomainName  $_ } | % { Get-ADDomainController -server $_.Name -filter * } | Select Name, Domain, Forest, IPv4Address, Site | ft

If you want just the Domain Controllers for the current domain  use this code (thanks to Harry Belafonte):

Get-ADDomainController -filter * | Select Name, Domain, Forest, IPv4Address, Site | ft

If you want to check for Domain Controllers of another domain - use this code. You'll need to supply a Domain server using -server filter

Get-ADDomainController -server myserver.net | Select Name, Domain, Forest, IPv4Address, Site | ft
