Quickly get the Domain Controllers via Powershell

I use this all the time, and get-adDomainControllers is a broken command, so this quickly grabs the DCs and can get other info if needed.

$AllDCS=[system.directoryservices.activedirectory.Forest]::GetCurrentForest().domains | %{$_.DomainControllers.name}

$AllDCS | foreach {

    Get-ADdomaincontroller $_.trim() | select Hostname, IPv4Address

    }
