7255N/A The best solution to solving installation and
7255N/A configuration issues is to take preventative measures by setting
7255N/A up logging files beforehand. The log files provide a
7255N/A source of hints and information that can be used to figure out
7255N/A what went wrong and how to fix the problem.

7255N/A Zone serial numbers are just numbers — they aren't
6443N/A date related. A lot of people set them to a number that
7255N/A represents a date, usually of the form YYYYMMDDRR.
6443N/A Occasionally they will make a mistake and set them to a
7255N/A "date in the future" then try to correct them by setting
7255N/A them to the "current date". This causes problems because
7255N/A serial numbers are used to indicate that a zone has been
7255N/A updated. If the serial number on the slave server is
7255N/A lower than the serial number on the master, the slave
7255N/A server will attempt to update its copy of the zone.
7255N/A Setting the serial number to a lower number on the master
7255N/A server than the slave server means that the slave will not perform
7255N/A updates to its copy of the zone.
7255N/A The solution to this is to add 2147483647 (2^31-1) to the
7255N/A number, reload the zone and make sure all slaves have updated to
7255N/A the new zone serial number, then reset the number to what you want
7255N/A it to be, and reload the zone again.
