I have been working on and off on this problem for 8 weeks now and I am completely baffled. Eight Road Runner techs have not been able to help me. I was adding a second 3COM NIC to my rig when I lost internet conectivity. Regardless of what page I try to go to in IE I get a "This page cannot be displayed" error. I have tried other browsers and they cannot get me on the net either. I can ping my ISP and they can ping me. I can ping the IP address for yahoo.com but I cannot ping their DNS name. As example: I can ping 216.32.74.51 but I cannot ping www.yahoo.com. I have reloaded W98SE 7 times. I have reloaded IE. I have done every trouble shooting tip on Tim Higgins site Praticallynetworked.com and the problem still remains. I have used four different brands of NICs. I have also used PCI and ISA NICs and placed them in different slots on the mobo. I have change IRQs for the NICs. I have even deleted some Windows 3COM system files and some Registry entires as suggested by Tim Higgins, but nothing has worked. I have put the cable modem on a Win 95 machine that I am typing on right now and the cable modens works fine. I can even set up a LAN between the W98SE and the Win95 computer and they can ping and see each other and pass files to each other using the same NICs that will not get me on the net. Tim's web page stated that trying to install two 3COM cards in the same computer has caused a lot of problems for a lot of people. That is exactly what I tried to do. I installed a 3COM ISA NIC card in my rig when there was already a 3COM PCI NIC card there. It seems when I did this that some setting in the computer got changed and I do not know where it is. Is there a way to make the computer recognize DNS names so my browser will work. Anybody got any ideas? Thanks for your imput.
