If the MAC address is not displaying in an ipconfig /all then I suspect it is something outside of the operating system. In this case the most likely culprit would be an iDRAC. If the iDRAC is set to shared then it will have it's own MAC address that will not be reported inside the OS, and it will be on the same physical port the server is connected through.
I suppose it could be iDRAC but then I would see the web interface at that IP address but I don't. I only just recently saw iDRAC for the first time on another machine so I'm not too familiar with it. Is there a way to check the iDRAC configuration from the OS or is the only way to do it during boot up? I have Windows Server 2008.
If you install OpenManage Server Administrator you can go to the remote access section and it will list the iDRAC MAC address and network configuration.
Yes. It is iDRAC. It has a static IP which is in my DHCP scope. Considering this server is a couple of years old, I'm really surprised this hasn't happened before. I changed the static IP and the problem is gone. It also now responds to pings on the new static IP.
