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.

IP Helper cannot be started under any conditions, if the following services are disabled, deleted or working improperly:
- NetIO Legacy TDI Support Driver
- Network Store Interface Service

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