Windows could not start the IIS Admin Service on Local Computer

Sometime when starting IIS I'm getting the following error:

Windows could not start the IIS Admin Service on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code -2147417831.

Event log is not much help:

The IIS Admin Service service terminated with service-specific error 2147549465 (0x80010119).

Solution:
Kill the inetinfo.exe process and start IIS again - that's it :)
