74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync The best solution to solving installation and
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync configuration issues is to take preventative measures by setting
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync up logging files beforehand. The log files provide a
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync source of hints and information that can be used to figure out
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync what went wrong and how to fix the problem.

74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync Zone serial numbers are just numbers — they aren't
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync date related. A lot of people set them to a number that
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync represents a date, usually of the form YYYYMMDDRR.
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync Occasionally they will make a mistake and set them to a
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync "date in the future" then try to correct them by setting
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync them to the "current date". This causes problems because
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync serial numbers are used to indicate that a zone has been
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync updated. If the serial number on the slave server is
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync lower than the serial number on the master, the slave
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync server will attempt to update its copy of the zone.
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync Setting the serial number to a lower number on the master
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync server than the slave server means that the slave will not perform
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync updates to its copy of the zone.
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync The solution to this is to add 2147483647 (2^31-1) to the
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync number, reload the zone and make sure all slaves have updated to
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync the new zone serial number, then reset the number to what you want
74fe172698ba936102e120dae998c9ebd09cfbdfvboxsync it to be, and reload the zone again.
