Restricted remote administration must be enabled for high-value systems.

Restricted remote administration features, RestrictedAdmin mode, and Remote Credential Guard for Remote Desktop Protocol (RDP), are an additional safeguard against "pass the hash" attacks, where hackers attempt to gain higher administrative privileges from a single compromised machine. Restricted remote administration protects administrator accounts by ensuring that reusable credentials are not stored in memory on remote devices that could potentially be compromised. When restricted remote administration is implemented, the local RDP service tries to log on to the remote device using a network logon, so the user's credentials are not sent across the network. Therefore, if the high-value IT resource is compromised, the credentials of the administrator connecting to the IT resource from the PAW are not compromised.
