Allows the redirection of Printers/Drives/Ports for RDP connections.

The recommended state for this setting is: Disabled.


In a security-sensitive environment, it is desirable to reduce the possible attack surface - preventing the redirection of COM, LPT and PnP ports will reduce the number of unexpected avenues for data exfiltration and/or malicious code transfer within an RDP session.


Printers, drives and ports (COM, LPT, PnP, etc.) will not be allowed to be redirected inside RDP sessions.


To establish the recommended configuration via GP, set the following UI path to: Disabled.
