Earlier today I had made a change to the allow-transfer clause on the master while trying to track down another issue and I forgot about it. Allow-transfer should, in almost all cases, be set to 'any;'. I still have some named issues that have me puzzled but, no doubt, these will eventually yield to further investigation. One source of problems is that some of the servers are CentOS-4.8 running Bind 9.2.4 while others are centOS-5.4 running Bind 9.3.6 and there are differences in how the named.conf file is parsed.
