Network Load Balancing not failing over properly

I have 2 MS 2012 servers setup in a NLB unicast configuration, with 2 NICs each on the same subnet.  When I take down the second server (and only the second server) the FQDN goes offline.  Below are the ipconfigs for each server.  Any help would be greatly appreciated!
