Cannot find an IP address

Question

I have a 4500s and I've had it for two years. Last year, I just plugged in my ethernet cord into my school's port and it was fine. This year I haven't been able to connect to the internet at all because no IP address can be found. I have a DAVICOM 9102-Based PCI Fast Ethernet Adapter. I brought my laptop with me and it connects to the internet perfectly fine but my 4500s won't. I've checked the device manager and it says my adapter is working properly, DHCP is enabled, etc. The tech guys at my school have come to check out my comp and they can't find anything wrong with the adapter. I've reformated and still no results. When I look at the status of the LAN (like IP address, Gateway, DNS, etc) all of them are unavailable or sometimes I will get a 169.254.. IP address. It won't ping any results, nada. Since it says everything is working fine, I don't know what the problem is or how to fix it. Oh yeah, when I plug in my ethernet cord, the green diagnostic light comes on. So what is the problem?

Oh yeah, when I was reformatting, the NIC drivers listed were for other network adapters. None were DAVICOM. They were Intel, CNET, and GVC. Just wondered if that has anything to do with it.

Try downloading and running winsock fix from the following site:

Are you sure you have a Davicom ethernet adapter? I've never seen these installed on a Dell. Did it come with your computer or did you install it later?

The tech guys at my school ran winsock (didn't do anything) and I just ran it from that site you gave me. It wouldn't go through completely. It said that the registry import could not be found. and then ended with an error 53.

I haven't installed a new one. That's the one that came with my Dell. I'm baffled too because I've looked for the davicom on dell and it's nowhere to be found. I only used the resource CD disk to reinstall my drivers when I reformated. And even before I reformatted, it was the davicom.

To troubleshoot your NIC, try pinging 127.0.0.1. (This is the loopback address built into the TCP/IP stack). If this fails, something is corrupt in the TCP/IP stack on your computer. Next try pinging yourself, i.e., the IP address assigned by your DHCP server. If that fails, the problem is definitely your NIC.
