In my previous post, I listed user group membership in AD and now we will visit the other side of the street. Here is a PowerShell script to list target group members in Active Directory
$root=([ADSI]"").distinguishedName
# You can change Domain Admins to any group interested and of course modify the path
$Group = [ADSI]("LDAP://CN=Domain Admins, CN=Users,"+ $root)
$Group.member
