Cannot make Internet connection either on my Admin account or Standard account

I logged out of my Mac admin user and use a standard Mac account.  I noticed I cannot connect to Internet on any browser or application.  Even Norton cannot make live update.  I noticed that all the Norton setting are greyed out so cannot do anything.

I exited and logged back to my Mac admin account and then I cannot connect to Internet anymore, even the Norton live update cannot connect.  Still all the allowed applications and connections are still there and configured.

What do you suggest?
