Description
Personnel who are system administrators must log on to domain systems only using accounts with the minimum level of authority necessary. Only system administrator accounts used exclusively to manage domain workstations may be members of an administrators group for domain workstations. A separation of administrator responsibilities helps mitigate the risk of privilege escalation resulting from credential theft attacks.

If any account listed in a domain workstation administrator group is a member of other administrator groups including the Enterprise Admins group, the Domain Admins group, or domain member server administrator groups, this is a finding.
