cb2846ded4de1abbb5934b92132baf826f1babfebnicholes The best solution to solving installation and
ac7985784d08a3655291f24f711812b4d8b1cbcffuankg configuration issues is to take preventative measures by setting
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes up logging files beforehand. The log files provide a
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes source of hints and information that can be used to figure out
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes what went wrong and how to fix the problem.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes Zone serial numbers are just numbers — they aren't
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes date related. A lot of people set them to a number that
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes represents a date, usually of the form YYYYMMDDRR.
ac7985784d08a3655291f24f711812b4d8b1cbcffuankg Occasionally they will make a mistake and set them to a
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes "date in the future" then try to correct them by setting
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes them to the "current date". This causes problems because
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes serial numbers are used to indicate that a zone has been
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes updated. If the serial number on the slave server is
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes lower than the serial number on the master, the slave
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes server will attempt to update its copy of the zone.
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes Setting the serial number to a lower number on the master
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes server than the slave server means that the slave will not perform
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes updates to its copy of the zone.
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes The solution to this is to add 2147483647 (2^31-1) to the
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes number, reload the zone and make sure all slaves have updated to
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes the new zone serial number, then reset the number to what you want
cb2846ded4de1abbb5934b92132baf826f1babfebnicholes it to be, and reload the zone again.
