5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews configuration issues is to take preventative measures by setting
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews up logging files beforehand. The log files provide a
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews source of hints and information that can be used to figure out
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews what went wrong and how to fix the problem.

fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User Zone serial numbers are just numbers-they aren't date
7e71f05d8643aca84914437c900cb716444507e4Tinderbox User related. A lot of people set them to a number that represents a
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User date, usually of the form YYYYMMDDRR. A number of people have been
5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews testing these numbers for Y2K compliance and have set the number
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User to the year 2000 to see if it will work. They then try to restore
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User the old serial number. This will cause problems because serial
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User numbers are used to indicate that a zone has been updated. If the
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User serial number on the slave server is lower than the serial number
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User on the master, the slave server will attempt to update its copy of
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User Setting the serial number to a lower number on the master
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User server than the slave server means that the slave will not perform
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User updates to its copy of the zone.
fd2597f75693a2279fdf588bd40dfe2407c42028Tinderbox User The solution to this is to add 2147483647 (2^31-1) to the
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User number, reload the zone and make sure all slaves have updated to
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User the new zone serial number, then reset the number to what you want
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User it to be, and reload the zone again.
