aa1d397c4736cd86540555193d71e55fa3b37b2aMark Andrews The best solution to solving installation and
d145b64cacc8d9cda51f9924ec70cd4661c3e2cfAutomatic Updater configuration issues is to take preventative measures by setting
bb93c8542756719b53096b9939e4041d0966026fAutomatic Updater up logging files beforehand. The log files provide a
2a31bd531072824ef252c18303859d6af7451b00Francis Dupont source of hints and information that can be used to figure out
2a31bd531072824ef252c18303859d6af7451b00Francis Dupont what went wrong and how to fix the problem.

4d0520004a9663324a6a30f2d1716565e6d0024cAutomatic Updater Zone serial numbers are just numbers — they aren't
7af91d15b2ce1ce32f7320f6d5cc3b83621c241aAutomatic Updater date related. A lot of people set them to a number that
c651f15b30f1dae5cc2f00878fb5da5b3a35a468Mark Andrews represents a date, usually of the form YYYYMMDDRR.
ce9cad6bb04869c5e94d9dc721032b25117f9210Automatic Updater Occasionally they will make a mistake and set them to a
7af91d15b2ce1ce32f7320f6d5cc3b83621c241aAutomatic Updater "date in the future" then try to correct them by setting
efb0e886f18894a1d2489f1ad74ad14b579e11c7Mark Andrews them to the "current date". This causes problems because
efb0e886f18894a1d2489f1ad74ad14b579e11c7Mark Andrews serial numbers are used to indicate that a zone has been
aa1d397c4736cd86540555193d71e55fa3b37b2aMark Andrews updated. If the serial number on the slave server is
91216cff91b34c9ff6e846dc23f248219cafe660Andreas Gustafsson lower than the serial number on the master, the slave
aa1d397c4736cd86540555193d71e55fa3b37b2aMark Andrews server will attempt to update its copy of the zone.
aa1d397c4736cd86540555193d71e55fa3b37b2aMark Andrews Setting the serial number to a lower number on the master
91216cff91b34c9ff6e846dc23f248219cafe660Andreas Gustafsson server than the slave server means that the slave will not perform
aa1d397c4736cd86540555193d71e55fa3b37b2aMark Andrews updates to its copy of the zone.
bb93c8542756719b53096b9939e4041d0966026fAutomatic Updater The solution to this is to add 2147483647 (2^31-1) to the
bb93c8542756719b53096b9939e4041d0966026fAutomatic Updater number, reload the zone and make sure all slaves have updated to
ce9cad6bb04869c5e94d9dc721032b25117f9210Automatic Updater the new zone serial number, then reset the number to what you want
5ae0e2c8b72fa44237edeb37d1945b1c3535ca39Automatic Updater it to be, and reload the zone again.
