Get FSMO Roles with PowerShell

The other day I needed to see what servers held which FSMO roles. I know there are many ways to get to this information. The easiest that I know of is using the NetDom resource kit utility.

netdom.exe query fsmo

I however wanted to see if I could use only .NET and not totally rely on any other tools. This was more of a challenge than anything else. I found several ways in .NET to get this info but I settled on this because it seemed the easiest way. If you know of an easier or more efficient way let me know.

   1:  $DCs = ([System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()).DomainControllers

   2:  $DCs | % { if ($_.Roles -ne '') {

   3:          "Server $_ has roles:"

   4:          ""

   5:          foreach ($role in $_.roles) {

   6:              $role.tostring().padleft($role.tostring().length + 10)

   7:          }

   8:          ""

   9:      }

  10:  }

The script is not as fast as NetDom, about 1 sec slower in my environment, but it depends only on .net.
