Get the Active Directory functional levels/FSMO roles forest wide
Description

With the following script, it is possible in the same array to get useful Active Directory informations such as:

  • domain names (DNS fqdn)
  • domain functional level
  • forest functional level
  • fsmo roles

The powershell cmdlets used for this script are the get-adforest and get-addomain. The documentation for these cmdlets can be found here and here.

After that I use the select-object cmdlet (alias: select) to build my array.

The script
import-module act*
$array=@()
$ForestInfo = get-adforest
$ForestADLevel = $ForestInfo.ForestMode
$domains = $ForestInfo.Domains
$domains | % {
	$array += get-addomain $_ | select @{n='DomainName';e={$_.DNSRoot}}, ` #Domain name
					DomainMode, @{n='ForestMode';e={$ForestADLevel}}, ` #Domain/Forest AD functional level
					PDCEmulator,InfrastructureMaster,RIDMaster,@{n='SchemaMaster';e={$ForestInfo.SchemaMaster}},@{n='DomainNamingMaster';e={$ForestInfo.DomainNamingMaster}} #FSMO role holders
}

The script has been tested successfully on a server running on Windows Server 2012R2
