I had a user call being unable to open any webpage that has a login tied to it. Gets a "page cannot be displayed" message. I had him check his antivirus, firewall (Windows firewall, no antivirus). We checked his internet settings in both IE and Mozilla. He gets this any way he accesses the internet, wireless or hard connection. Gets it at any location. Has second laptop that does access web sites involving login.
Does any one have any other ideas?
