Default Behavior

IP Helper is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the IP Helper service is running as LocalSystem in a shared process of svchost.exe along with other services. If IP Helper fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the iphlpsvc service has failed to start due to the error.

While IP Helper is stopped, the Network Connectivity Assistant service cannot be launched.
