Ethernet Port not working on Notebook
Hello, I have a customer's Compaq notebook, Windows 8.1, and there is a problem with the Realtek FE Family ethernet controller.
It just won't configure itself with DHCP. WIFI works perfectly instead.
Here's what I have already tried:
changing the cable
changing the port on the router
changing the router
resetting winsock
resetting tcp/ip
removing the driver and installing the latest version
ipconfig /release
ipconfig /renew
When I try resetting tcp/ip, it gives an error where it says "access denied" but it doesn't specify the component the error is related to.
So can somebody help me out? Faulty port maybe?

The dhcp server is configured on my Mikrotik router and works fine with more than 15 devices I have hooked up right now.
I have already tried disabling Wifi but nothing changed. I will try to boot a Live cd since disabling IPv6 didn't work either.

Try to use static IP on that notebook for troubleshooting purpose ping the DHCP server did it reply?

I just noticed that the Mac Address in the screenshot I posted is a sequence of twelve 0s.
Also, I booted with Lubuntu and it sees the Mac Address the same way and there is no connection either, so I guess it's the ethernet card after all.

The nic may damaged or incompatible
Thanks, but what was the source of the problem?
ASKER
As you said, damaged nic, there's no other explanation. It wont' work with DHCP, fixed IP, different routers on different networks, different OSes.
Since there was no real solution, I gave points to all the people who tried to help.

I have not tried manual IP, mostly because my customer needs Dhcp to work.
@McKnife: I will try both and report.
