I have a computer Dell Optiplex GX520 with IE7. All of a sudden this computer will not connect to the internet. It is connected to a local network with DHCP. It started acquiring an invalid IP address like 164.XXX.XXX.XXX. It is a number not assigned by our DHCP server. I went in and assigned a static IP address and it will then connect to the local network. For instance, I can see file servers and printers, but when I try to access IE, IE will open but nothing shows. I get a message that cannot be displayed or cannot connect. I have uninstalled the ethernet card and updated the driver, but it still won't connect. I know that the network is working because I can access other computers and file servers. But I am at a lost as to why I can't get on the internet. I can't update IE because I can't get online. I have run Mal Ware Bytes and SuperSpyWare and computer comes clean. Of course I can't get the latest update because I can't get online. I have several of these computers, so I took the hard drive out and installed it in another computer, and the problem follows the hard drive. So there is something about settings, or software, or configuration on the hard drive that has a problem. Has anyone experienced this frustrating problem? I really do not want to reformat and install everything. I would really appreciate any help with this.
