Not trying to do anything special:
PS C:\Users\schtask> Get-ADGroupMember "STSS Staff"
Get-ADGroupMember : The specified directory service attribute or value does not
exist
At line:1 char:18
+ Get-ADGroupMember <<<< "STSS Staff"

ember], ADException

I think there might be more at play, because any normal account I choose, it doesn't even see the Domain Admins group (domain changed to something generic for post)
PS C:\Users\schtask> Get-ADGroupMember "Domain Admins"
