1f1b6bf13313fdd14a45e52e553d3ff28689b717coar The best solution to solving installation and
1f1b6bf13313fdd14a45e52e553d3ff28689b717coar configuration issues is to take preventative measures by setting
265f930c2f2121bc51d5ea27865ded2759a78416gryzor up logging files beforehand. The log files provide a
265f930c2f2121bc51d5ea27865ded2759a78416gryzor source of hints and information that can be used to figure out
265f930c2f2121bc51d5ea27865ded2759a78416gryzor what went wrong and how to fix the problem.

265f930c2f2121bc51d5ea27865ded2759a78416gryzor Zone serial numbers are just numbers-they aren't date
265f930c2f2121bc51d5ea27865ded2759a78416gryzor related. A lot of people set them to a number that represents a
265f930c2f2121bc51d5ea27865ded2759a78416gryzor date, usually of the form YYYYMMDDRR. A number of people have been
265f930c2f2121bc51d5ea27865ded2759a78416gryzor testing these numbers for Y2K compliance and have set the number
265f930c2f2121bc51d5ea27865ded2759a78416gryzor to the year 2000 to see if it will work. They then try to restore
265f930c2f2121bc51d5ea27865ded2759a78416gryzor the old serial number. This will cause problems because serial
265f930c2f2121bc51d5ea27865ded2759a78416gryzor numbers are used to indicate that a zone has been updated. If the
265f930c2f2121bc51d5ea27865ded2759a78416gryzor serial number on the slave server is lower than the serial number
265f930c2f2121bc51d5ea27865ded2759a78416gryzor on the master, the slave server will attempt to update its copy of
265f930c2f2121bc51d5ea27865ded2759a78416gryzor Setting the serial number to a lower number on the master
265f930c2f2121bc51d5ea27865ded2759a78416gryzor server than the slave server means that the slave will not perform
265f930c2f2121bc51d5ea27865ded2759a78416gryzor updates to its copy of the zone.
265f930c2f2121bc51d5ea27865ded2759a78416gryzor The solution to this is to add 2147483647 (2^31-1) to the
265f930c2f2121bc51d5ea27865ded2759a78416gryzor number, reload the zone and make sure all slaves have updated to
265f930c2f2121bc51d5ea27865ded2759a78416gryzor the new zone serial number, then reset the number to what you want
265f930c2f2121bc51d5ea27865ded2759a78416gryzor it to be, and reload the zone again.
