I have NIS2010 since October/November and yesterday I installed the windows vista Service pack 2. Today I couldn't open any webpage on any browser i got (explorer, chrome and mozilla). My internet connection is working normally, I can log in to skype, but I can't open any webpage. not even google.com. The browser starts to open it, but then it takes too long and nothing happens.
How can I fix this? I can't run windows live update and even norton update.
Thanks
