IE / Web pages problem / page cannot be displayed. Suddenly, when I open Ineternet Exporer I get the “The page cannot be displayed” message. All was working fine before today. I know I can call the IT support people but I want to know how to fix it. Therefore, any troubleshooting technique would be appreciated. When I type ipconfig in the command promp I get the following: <… Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : ho.lloydstsb.co.uk IP Address. . . . . . . . . . . . : 10.160.131.189 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 10.160.131.1 ….> When I open IE, click on Tools  internet Options,  Connections tab  LAN settings button, I get the following: The <use Automatic Configuration Script > option is ticked and the following is in the address field: file://c:\_itconf\proxy.pac this has always been there and it worked before. If I ping www.bbc.com I get request timed out. If I ping 127.0.0.1 it is ok. I get 0 packet lost. Thank you in advance

I really don't think it should matter, but, you have a class A ip address and class C subnet. Try changing your subnet to 255.0.0.0
