7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User>The best solution to solving installation and
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User configuration issues is to take preventative measures by setting
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User up logging files beforehand. The log files provide a
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User source of hints and information that can be used to figure out
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User what went wrong and how to fix the problem.</P

7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User>Zone serial numbers are just numbers-they aren't date
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User related. A lot of people set them to a number that represents a
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User date, usually of the form YYYYMMDDRR. A number of people have been
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User testing these numbers for Y2K compliance and have set the number
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User to the year 2000 to see if it will work. They then try to restore
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User the old serial number. This will cause problems because serial
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User numbers are used to indicate that a zone has been updated. If the
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User serial number on the slave server is lower than the serial number
7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User on the master, the slave server will attempt to update its copy of

7911e6f9de303bca5a3d8b34f4330c8f7cecffaeTinderbox User server than the slave server means that the slave will not perform
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User updates to its copy of the zone.</P
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User>The solution to this is to add 2147483647 (2^31-1) to the
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User number, reload the zone and make sure all slaves have updated to
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User the new zone serial number, then reset the number to what you want
1e9517ea2156b990be21f44676d3370318eacf17Tinderbox User it to be, and reload the zone again.</P
