Create WMI filter that will identify devices for each tier. In the article three tiers are used, domain controllers, servers and workstations. This provides a balance between security and simplification but this can easily be extended to other devices or server types.
Create a group for each tier. This will hold the members for each tier.
Create a group policy for each tier. It should filter based on the tier type and will contain the allow/deny rules.
Finally, add your dedicated DA accounts to tier 0 group, dedicated server administrators accounts to tier 1 group. Accounts will now only be able to log in locally or via RDP if they are meant for the specific tier
