I have a wired windows 2003 domain. I have once client who cannot connect to the network. In the local area connection status it shows that it is trasmitting packets but not receiving them. So far, it has sent 845 packets and received 0. It can ping itself, but not onto the network. I have tried a different cable and a different port on the switch. Any ideas what it could be besides hardware? It is an onboard NIC on a laptop, so I can't just install another one.
