Limited or no connectivity

I have a laptop in a Windows Domain that is connecting via wireless but will not connect to our wired LAN. This is a new issue as it has always worked before. I have uninstalled the NIC, updated the drivers, ran the repair, verified that Automatically Detect DHCP and DNS are selected, run an IPCONFIG /flushdns, and IPCONFIG /registerdns, disjoining it from the domain, rejoining it to the domain, re-imaging the computer completely, and running enough MS Fixit tools to choke a donkey. The ethernet connection will work sporadically for 2-20 minutes, but will always lose its IP and go back to the APIPA address in the 169.x.x.x. range.

It could be a faulty NIC in the laptop. Could you possibly get a USB->Ethernet adapter to try?

Just for trouble shooting purposes, have you tried assigning a static address? Just to see if you could establish a connection?

Yes, I did add a static address, but had the same limited results. I am testing a USB NIC on it now and it seems to be working. I'm going to be very disappointed if it is a faulty NIC.

If a static address did not give you a connection, I would be close to saying its dead.

However, the link that was posted above does detail how to repair the Winsock registry entries. Maybe try that?

Also, just wanted to make sure you have tried this connection with multiple Cat5 cables in multiple ports that you know are functioning. Just in case.
