I have a cable modem connection and cannot seem to get a valid IP address. This occured after a corrupt /winnt/system32/config/system error came up which I solved it by replacing the file with a default one. Now I cannot get a valid IP address when the NIC is connected to my cable modem. My address is like 169.254.xx.xx. I have Windows 98 on a second partition and the NIC/cable modem works fine, I can get a valid IP address. How can I fix this? I cannot get a valid IP for my NIC under windows xp ever since I replace the old system file with the default one. There must be something in the old system file that is missing in the new system file. Any ideas would be great. I tried repairing the connection but it failed too. It's not hardware, it's more of a windows xp problem. Also what is the equivalent of the command <b>nslookup</b> in windows xp for windows 98? I'm goin to try to put in the IP manually in winxp but cannot find the address of the DNS server under windows 98. WHat's the command line? In windows xp I used nslookup.
