3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley The best solution to solving installation and
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley configuration issues is to take preventative measures by setting
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley up logging files beforehand. The log files provide a
036f4a76ec5e5bdba8a7d2f7e77c188a8246bbacBob Halley source of hints and information that can be used to figure out
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley what went wrong and how to fix the problem.

3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley Zone serial numbers are just numbers — they aren't
036f4a76ec5e5bdba8a7d2f7e77c188a8246bbacBob Halley date related. A lot of people set them to a number that
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley represents a date, usually of the form YYYYMMDDRR.
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley Occasionally they will make a mistake and set them to a
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley "date in the future" then try to correct them by setting
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley them to the "current date". This causes problems because
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley serial numbers are used to indicate that a zone has been
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley updated. If the serial number on the slave server is
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley lower than the serial number on the master, the slave
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley server will attempt to update its copy of the zone.
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley Setting the serial number to a lower number on the master
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley server than the slave server means that the slave will not perform
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley updates to its copy of the zone.
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley The solution to this is to add 2147483647 (2^31-1) to the
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley number, reload the zone and make sure all slaves have updated to
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley the new zone serial number, then reset the number to what you want
3da473e3e96d2d054331b43519426a9b5f83cf4cBob Halley it to be, and reload the zone again.
