Default Behavior

IP Helper is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the IP Helper service is running as LocalSystem in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If IP Helper fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the iphlpsvc service is not running because of the error.

Dependencies

IP Helper is unable to start, if at least one of the following services is stopped or disabled:

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.

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

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 changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
