cd348e325366620fe047edcc849e3c9424828599Peter Bray The best solution to solving installation and
cd348e325366620fe047edcc849e3c9424828599Peter Bray configuration issues is to take preventative measures by setting
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray up logging files beforehand. The log files provide a
cd348e325366620fe047edcc849e3c9424828599Peter Bray source of hints and information that can be used to figure out
0ca9a2c194523c517c3aafe5758e217ac88d6baaLubos Kosco what went wrong and how to fix the problem.

d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray Zone serial numbers are just numbers-they aren't date
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray related. A lot of people set them to a number that represents a
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray date, usually of the form YYYYMMDDRR. A number of people have been
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray testing these numbers for Y2K compliance and have set the number
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray to the year 2000 to see if it will work. They then try to restore
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray the old serial number. This will cause problems because serial
cd348e325366620fe047edcc849e3c9424828599Peter Bray numbers are used to indicate that a zone has been updated. If the
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray serial number on the slave server is lower than the serial number
cd348e325366620fe047edcc849e3c9424828599Peter Bray on the master, the slave server will attempt to update its copy of
cd348e325366620fe047edcc849e3c9424828599Peter Bray Setting the serial number to a lower number on the master
cd348e325366620fe047edcc849e3c9424828599Peter Bray server than the slave server means that the slave will not perform
cd348e325366620fe047edcc849e3c9424828599Peter Bray updates to its copy of the zone.
cd348e325366620fe047edcc849e3c9424828599Peter Bray The solution to this is to add 2147483647 (2^31-1) to the
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray number, reload the zone and make sure all slaves have updated to
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray the new zone serial number, then reset the number to what you want
d2a02e104622a26dd90fa88f4f17188f2039809fPeter Bray it to be, and reload the zone again.
