36488004520b3a22fbd37ef8e10e5641be154ac1slive The best solution to solving installation and
36488004520b3a22fbd37ef8e10e5641be154ac1slive configuration issues is to take preventative measures by setting
36488004520b3a22fbd37ef8e10e5641be154ac1slive up logging files beforehand. The log files provide a
36488004520b3a22fbd37ef8e10e5641be154ac1slive source of hints and information that can be used to figure out
36488004520b3a22fbd37ef8e10e5641be154ac1slive what went wrong and how to fix the problem.

36488004520b3a22fbd37ef8e10e5641be154ac1slive Zone serial numbers are just numbers — they aren't
36488004520b3a22fbd37ef8e10e5641be154ac1slive date related. A lot of people set them to a number that
36488004520b3a22fbd37ef8e10e5641be154ac1slive represents a date, usually of the form YYYYMMDDRR.
36488004520b3a22fbd37ef8e10e5641be154ac1slive Occasionally they will make a mistake and set them to a
36488004520b3a22fbd37ef8e10e5641be154ac1slive "date in the future" then try to correct them by setting
36488004520b3a22fbd37ef8e10e5641be154ac1slive them to the "current date". This causes problems because
36488004520b3a22fbd37ef8e10e5641be154ac1slive serial numbers are used to indicate that a zone has been
36488004520b3a22fbd37ef8e10e5641be154ac1slive updated. If the serial number on the slave server is
36488004520b3a22fbd37ef8e10e5641be154ac1slive lower than the serial number on the master, the slave
36488004520b3a22fbd37ef8e10e5641be154ac1slive server will attempt to update its copy of the zone.
36488004520b3a22fbd37ef8e10e5641be154ac1slive Setting the serial number to a lower number on the master
36488004520b3a22fbd37ef8e10e5641be154ac1slive server than the slave server means that the slave will not perform
36488004520b3a22fbd37ef8e10e5641be154ac1slive updates to its copy of the zone.
36488004520b3a22fbd37ef8e10e5641be154ac1slive The solution to this is to add 2147483647 (2^31-1) to the
083c5339583e94bf811cf61bdbc1dbc6a382a89edpejesh number, reload the zone and make sure all slaves have updated to
36488004520b3a22fbd37ef8e10e5641be154ac1slive the new zone serial number, then reset the number to what you want
36488004520b3a22fbd37ef8e10e5641be154ac1slive it to be, and reload the zone again.
