Windows 7: Yellow Triangle on Network Icon

A few weeks ago I posted that I was having Network issues. There would always be a yellow triangle on the Network Icon in the System Tray but it never stopped me from connecting to the internet. Once connected the triangle would go away and everything was OK. Once you reboot the triangle is back, etc, etc...
I thought the "Rename Homegroup" tweak was causing the problem because it seemed to start on the reboot after that. I WAS WRONG!! What I forgot was that I also Enabled NIS 2010 "Privacy Control" before the reboot.
I have just disabled "Privacy Control" rebooted, and everything is now OK.
I tested the theory by Enabling "Privacy Control" reboot back again, Disable, reboot gone again.

I presume NIS = Norton Internet Security?

Yes Norton Internet Security 2010
