Nice simple three liner here. I often want to check how many users are in a particular group, and find it a bit annoying that ADUC doesn’t show this in the Group Properties. So to find out, run this from a Powershell window on a DC:

Import-Module ActiveDirectory
$group = Get-ADGroupMember "group name" -recursive | Select-Object name
$group.count

The second line puts all the members into a variable called $group, and if you didn’t already know, putting .count after any variable will enumerate the objects in that variable 🙂

Happy days!
