Hi all, i just upgraded my motherboard and cpu for my Unraid Servo.  Once i got everything booted up, i was unable to connect over the network using the server name or former IP address.  My new motherboard is a Gigabyte GA-X99-Ultra with Intel Gbe and Killer e2400 nics.  I plugged in both ports but still am unable to login to the server.  I've attached my syslog for details.  Thanks.

I should correct myself, it says "eth0 does not exist"

Your two Ethernet ports start off as eth0 and eth1:

 

Jul  7 08:21:02 Servo kernel: alx 0000:0a:00.0 eth0: Qualcomm Atheros AR816x/AR817x Ethernet [1c:1b:0d:07:8f:0f]

...

Jul  7 08:21:02 Servo kernel: e1000e 0000:00:19.0 eth1: registered PHC clock

 

but they get shuffled around and finally settle as eth2 and eth3:

 

Jul  7 08:21:02 Servo kernel: alx 0000:0a:00.0 eth120: renamed from eth0

Jul  7 08:21:02 Servo kernel: alx 0000:0a:00.0 eth2: renamed from eth120

Try disabling the non-Intel port and post your full diagnostics zip.

 

Ok so in the bios, there was an option to enable/disable "PCH Internal LAN" which is described as "Enables or disables the onboard LAN function. (Default: Enabled)

If you wish to install a 3rd party add-in network card instead of using the onboard LAN, set this item to Disabled."  Just by frustration i disabled this function and the server came online.  Thanks for the tips, i'll leave this here in case someone else has this odd problem.
