Network computer down -- not receiving incoming packets

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: [00000008] 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.

Can you verify that the switch the computer is plugged into is okay?  I'd move the computer to a different port just to make sure the port isn't the problem.

Good Morning,
Another suggestion is to uninstall and then allow Windows to re-detect the NIC.

Hello,

Please try the following:

Step 1. As Jimmyray suggested change the port on the switch - ideally with a known good machine - if that doesnt work then you know the card is at fault. If not proceed to step 2.
Step 2. Flush the DNS: Start > Run > CMD > ipconfig /flushdns
Step 3. Replace the NIC drivers.
Step 4. Remove all thrid party/Microsoft firewalls temporarily.
Step 5. Ensure that there are no false entries in the NIC properties - such as DNS servers etc...

Let me know how you get on and I will monitor this post.

Thanks

Good Morning,

Since two of Richard1985's suggestions were based on other's previous posts, I am curious as to what was the ultimate solution.  Can you please detail what resolved the problem?

Thanks,
LJ
