In the last few days, I have experienced problems wth accessing web pages on the first or second attempt. To my knowledge, there have been no operating system changes (XP HE with SP2) or software updates to the browsers or ESET firewall. With IE7, I get a "Internet Explorer cannot display the webpage" error. With Firefox 3, I get an "Address Not Found" error. When I refresh (or press 'Try Again' for FF3) the page will often load, but sometimes I have to refresh 2 or 3 times before it works. I have tried deleting both browsers in the ESET firewall rules, and then re-adding them (as suggested on the Mozilla site), but this has made no difference. There doesn't appear to be a problem with my internet connection (e.g. I can stream an audio file with no problems). Grateful for any advice - many thanks.
