Windows xp Hi I have been having problems with my connection to the internet, about a week ago i tried to go online but i had the "page cannot be displayed" screen, i tried everything, then restored my pc to an earlier time, that seemed to fix the problem. then it happened again, but this time the restore didnt work, i checked everything, the modem had disappeared from my network connection list. i tried to install the modem again but couldnt as the disc needs to connect to the internet to complete the installation, i found eventually that the firewall setting on zonealarm had jumped to high, so i adjusted it to medium, it worked fine, although was running through an old network setting? and today i cannot connect my partner has checked all the things we tried b4 but nothing works! i cant understand why tsettings keep changing and disappearing all of a sudden My pc has shield delux security witch i purchased last month and zone alarm witch i downloaded free off the internet i have never had these problems ever before , both the security i have on my pc have worked fine? Please help Rachael
