Default Behavior
Peer Name Resolution Protocol is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Peer Name Resolution Protocol service is started, it runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If Peer Name Resolution Protocol fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the PNRPsvc service hasn't been started.
