I did try that driver but it did not fix the issue. 

Doing some further digging around.  It looks like the server has IP 
connectivity from another server on the same network segment, but it is 
traffic going over network switches that has problems.  I am trying to 
figure out what the problem is precisely, may be ARP or something similar. 

Ideas??
