78a072e1b56619e3230735ae073668311232ec94vboxsync The best solution to solving installation and
78a072e1b56619e3230735ae073668311232ec94vboxsync configuration issues is to take preventative measures by setting
78a072e1b56619e3230735ae073668311232ec94vboxsync up logging files beforehand. The log files provide a
78a072e1b56619e3230735ae073668311232ec94vboxsync source of hints and information that can be used to figure out
what went wrong and how to fix the problem.

<p>
Zone serial numbers are just numbers &#8212; they aren't
date related. A lot of people set them to a number that
represents a date, usually of the form YYYYMMDDRR.
Occasionally they will make a mistake and set them to a
"date in the future" then try to correct them by setting
them to the "current date". This causes problems because
serial numbers are used to indicate that a zone has been
updated. If the serial number on the slave server is
lower than the serial number on the master, the slave
server will attempt to update its copy of the zone.
</p>
<p>
Setting the serial number to a lower number on the master
server than the slave server means that the slave will not perform
updates to its copy of the zone.
</p>
<p>
The solution to this is to add 2147483647 (2^31-1) to the
number, reload the zone and make sure all slaves have updated to
the new zone serial number, then reset the number to what you want
it to be, and reload the zone again.
