Hi all,
Our intranet's WAN interface just stopped working yesterday, and I can't figure it out.
The machine has a Gigabyte motherboard, with on-board RTL-8110SC/8169SC Gigabit Ethernet and D-Link PCI NIC for the LAN side. I can get into the LAN side without an issue, but can't see the WAN side at all.

So the driver is there, or so it seems. rmmod r8169 dropped both NIC's and I had to reboot the (headless) server to get the D-Link working again. Removing, and re-adding the eth0 interface with system-config-network doesn't actually re-create the NIC either.
So, how do I re-create it? Google search didn't reveal much, other that using the r8169 module, which is already loaded.
No changes were made to the server in a long time, that I know of, and it's running kernel 2.6.18-194.11.4.el5

Here's something interesting though:
