On a client's computer running Vista x86, he installed Norton Internet Security 2011, and the Internet stopped working. I took a look, and Internet Explorer and a fresh copy of Firefox are not connecting. I can ping addresses (such as www.google.com and msn.com), and I get the same replies back on that computer as a second computer on the same network. I uninstalled Norton, and both browsers started working. I tried a fresh download from the Norton website, installed it successfully, but still blocks the Internet.

The copy has NOT been activated yet, but I have a valid key with his receipt when he purchased it from Symantec. It has not asked for a key, but it's passed its period of working where it now wants it activated. Of course, with no Internet, it doesn't activate

Well, it's protecting him from the internet, right? What's the problem? :-) – Joe Internet Jul 21 '11 at 20:14
    
Not the point :P It doesn't get online, and Norton is blocking the settings page until it can activate ONLINE – Canadian Luke Jul 21 '11 at 20:35
    
Well, my first choice would be to dump Norton. Second would be to contact Symantec. I'm sure they've dealt with this before. – Joe Internet Jul 21 '11 at 20:40
    
That's what I'm doing now... And I'm teaching the tech how to do his job... – Canadian Luke Jul 21 '11 at 21:09
    
I should probably mention that it's not my computer, it's a customer's laptop. He has the email with the product key as well, so he obviously wants it installed – Canadian Luke Jul 21 '11 at 21:19
