I am a computer technician and a client of mine had problems with her computer. I swapped out the motherboard and installed a fresh copy of Windows XP Pro. SP2 w/ all latest updates. I had the PC at my house connected to my router to a cable modem and it retrieved an internet connection DHCP. No problem there... When I brought it to the clients business the internet connection was fine as well. They are running Windows XP Pro. SP2 w/ a Biostar P4VMA-M motherboard with an integrated NIC. The NIC is a VIA Rhine II Fast Ethernet Adapter. The PC is directly connected to the cable modem. After a day running smoothly her internet connection said "Limited or No Connectivity". The Windows Autoconfiguration assigned it an address of 169.xxx.xxx.xxx etc... I tried everything from uninstalling the NIC and loading newer drivers to resetting the WINSOCK. Restarted the PC, set a static IP address but that still didn't do the trick. I hooked up my laptop directly to the cable modem and my laptop was able to resolve the IP address as well as the DHCP server. Right now I do not know what to do.
This is my first post, so I am sure an Expert will need more info. Thanks.
