5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews The best solution to solving installation and
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.

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