I could log in to certain sites on the web but not to certain other sites. I tried changing the ISP. It does not work. I tried IE6 and Netscape 7.2. Still problem persists.
Which sites can you access, and which sites can you not? What reason does it give for refusing/failed access? Not much to give ideas on, unless your internet is filtered.
if using ie6 check your settings in :Tools -internet options - security tab.
also ensure you have 128 bit security. go to: Help - about internet explorer and look just below the version number.
Then Go to microsofts homepage and download the relevant patch
