DHCP Server showing '169' address

Recently I was on a Domain Controller and accessing the DHCP Server console, and I noticed that the server address was showing a 169 address instead of the server name.  DHCP was working fine and there was no issue with the way that it was all working, but it was rather odd that it was showing this address, so I decided to look into it further.

It turns out that the DHCP console was getting it's IP address from a NIC that wasn't in use, hence the 169 address.  A quick fix here was to disable the NIC itself.  After closing and re-opening (refresh would also suffice), DHCP showed the FQDN of the server, and it was back to normal.
