Since the connections all fail, call it in and follow the maker's instructions to the letter. It's under warranty so let it be their problem.
My Lenovo 3000 H500, 4233-63U, Windows EX Professional, with SP3, 32-bit system lost its Internet connection. I have tried everything: 1) disabling the Windows Firewall. 2) Changing the static IP address, 3) reducing the Security Zone to minimum, 4) running IPconfig (fine), 5) pinging Yahoo.com (gets a return), 6) pinging the Loopback IP 127.0.0.1 (worked fine), 7) uninstalled the NIC, and installed the latest driver from Web Site using "command.com," even installed FireFox browser thinking it was a fault in I.E. 8, 9) tried WiFi access (same error), 10) ran the Network Diagnostic tool, still cannot connect.
No matter what I have done, I keep getting: "Internet Explorer cannot display the webpage" message. I have both LAN and WiFi setup on our network, and neither one works(LAN is static IPs, and WiFi is dynamic).
Both Network Adapters say they are working properly, but neither accesses the Internet.
Two days ago, I could connect, and this Notebook is only four months old. All of my DNS and IPs are correct, and nobody can change them but I. All of my other 60 plus computer can get outside our router Verizon Actiontec Wireless for FIOS) and access the Internet.
But this one Notebook, all of a sudden, cannot.
I am a networking professional, and was Network Administrator over a 1900 LAN/WAN before, so I know Networking, but I am stumbed here. Sounds like a WINSOCK problem we used to have in the old Windows 3.1 systems, but I cannot pin-point this problem.
Any help would be appreciated, and thanks for taking the time to read this.
