Default Behavior

IP Helper is a Win32 service. In Windows 11 it starts automatically during the operating system startup. Then the IP Helper service logs on as LocalSystem and running in a shared process of svchost.exe. If IP Helper fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the iphlpsvc service startup failure.

Dependencies

If IP Helper doesn't work properly, the Network Connectivity Assistant service can't start.
