network connection checkbox grayed out in notification area

The network checkbox on the Notification Area tab of Taskbar and Start Menu Properties is grayed out and I have been unsuccessful correcting the problem.

I have done all of the following, with no success:

  1. All the methods - two, three, and four - that apply to my situation in http://www.vistax64.com/tutorials/106787-notification-area-system-icons.html
  2. Restored the system to the earliest point available.
  3. Ran sfc /scannow. The cbs.log file is attached.

What other things can I try to display the network icon in the system tray.
