5.17 Ensure 'PNRP Machine Name Publication Service (PNRPAutoReg)' is set to 'Disabled'


This service publishes a machine name using the Peer Name Resolution Protocol. Configuration is managed via the netsh context 'p2p pnrp peer'.

The recommended state for this setting is: Disabled.


Peer Name Resolution Protocol is a distributed and (mostly) serverless way to handle name resolution of clients with each other. In a high security environment, it is more secure to rely on centralized name resolution methods maintained by authorized staff.


Some peer-to-peer and collaborative applications, such as Remote Assistance, may not function.


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