Default Behavior

Peer Name Resolution Protocol is a Win32 service. In Windows 11 it starts only if the user, an application or another service starts it. When the Peer Name Resolution Protocol service is started, it logs on as NT AUTHORITY\LocalService and running in a shared process of svchost.exe. If Peer Name Resolution Protocol fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the PNRPsvc service startup failure.

Dependencies

Peer Name Resolution Protocol cannot be started, if the Peer Networking Identity Manager service won't start.

If Peer Name Resolution Protocol doesn't work properly, the following services will not start:
