Restricted Admin Mode

For helpdesk support scenarios in which personnel require administrative access via Remote Desktop sessions, it isn't recommended the use of Remote Credential Guard. If an RDP session is initiated to an already compromised client, the attacker could use that open channel to create sessions on the user's behalf. The attacker can access any of the user's resources for a limited time after the session disconnects.
We recommend using Restricted Admin mode option instead. For helpdesk support scenarios, RDP connections should only be initiated using the /RestrictedAdmin switch. This helps to ensure that credentials and other user resources aren't exposed to compromised remote hosts.
Because restricted admin mode can allow the usage of pass the hash techniques, it can be used to bypass MFA.
