Default Behavior

IP Helper is a Win32 service. In Windows 8 it is starting automatically during the operating system startup. Then the IP Helper service runs as LocalSystem in a process of svchost.exe, sharing it with other services. If IP Helper 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 iphlpsvc service hasn't been started.

Dependencies

IP Helper can't start, if any service from the list below is disabled or not available:

If IP Helper is disabled, the Network Connectivity Assistant service will not be started and initialized.

Restore Default Startup Configuration for IP Helper

Before you begin doing this, make sure that all the services on which IP Helper 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 commands below, paste them into the command window and press ENTER:

sc config iphlpsvc start= auto
sc start iphlpsvc

3. Close the command window and restart the computer.

The iphlpsvc service is using the iphlpsvc.dll file that is located in the %WinDir%\System32 folder. If the file is corrupted or deleted, you can put it back in there.
