Default Behavior

Peer Name Resolution Protocol is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Peer Name Resolution Protocol service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe along with other services. If Peer Name Resolution Protocol fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the PNRPsvc service has failed to start due to the error.

Dependencies

Peer Name Resolution Protocol cannot be started under any conditions, if the Peer Networking Identity Manager service is disabled.

While Peer Name Resolution Protocol is stopped, disabled or working incorrectly, the following services do not start:

Restore Default Startup Configuration for Peer Name Resolution Protocol

Before you begin doing this, make sure that all the services on which Peer Name Resolution Protocol depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config PNRPsvc start= demand

3. Close the command window and restart the computer.

The PNRPsvc service is using the pnrpsvc.dll file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
