    It should work using files but are you 100% sure all name resolution works via your hosts files - FQDN and short names, forward and reverse. Also can each server resolve itself - FQDN, short, forward and reverse? Andrew

    I notice that you are using uppercase hostnames.
    Can you confirm that all entries in hosts files and NBU match exactly? 

    How did you go about adding hosts entries to the Appliance?
    Bear in mind that the Appliance expect to have a shortname as well as FQDN in hosts file. 
    Adding entries via the CLISH expects this format:
    Hosts Add <ip> <FQDN> <short_name>

    One more thing - did you remember to clear NBU host cache after adding hosts entries?
