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

Information

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.

Rationale:

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.

Impact:

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

Solution

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

Computer Configuration\Policies\Windows Settings\Security Settings\System Services\PNRP Machine Name Publication Service

Default Value:
