I recently upgraded a pc from windows xp home to windows server 2003. Before the upgrade the computer was able to get out to the internet. After the update that did not have any errors. The server is not able to join the domain and can not get out to the internet. The server is not able to pull an IP from the network. The NIC is showing a dummy ip address and the MAC address is all Zero's. I am at my wits end with this problem any help you can all give me would be greatly appreciated.
