I have a PC that's connected to our LAN, and about an hour ago, it went down. If I go into Network Connections, click on Local Area Connection, and choose Status, what I see is packets being sent but no packets being received. The connection has an IP address. I've tried the obvious things, clicking Repair to fix the connection (Windows says that the repair was successful), restarting the computer, unplugging the router, but none of that worked. I ran Network Diagnostics and the message I got under network adapters:  Realtek RTL8168C(P)/8111C(P) PCI-E Gigabit Ethernet NIC: FAILED.
Unfortunately. this computer is the one in the office that holds all of our files, so we really need to get it back up and running, but I don't know what to do. Does anybody have some suggestions? Thanks.
