ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync The best solution to solving installation and
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync configuration issues is to take preventative measures by setting
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync up logging files beforehand. The log files provide a
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync source of hints and information that can be used to figure out
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync what went wrong and how to fix the problem.

ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync Zone serial numbers are just numbers-they aren't date
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync related. A lot of people set them to a number that represents a
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync date, usually of the form YYYYMMDDRR. A number of people have been
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync testing these numbers for Y2K compliance and have set the number
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync to the year 2000 to see if it will work. They then try to restore
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync the old serial number. This will cause problems because serial
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync numbers are used to indicate that a zone has been updated. If the
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync serial number on the slave server is lower than the serial number
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync on the master, the slave server will attempt to update its copy of
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync Setting the serial number to a lower number on the master
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync server than the slave server means that the slave will not perform
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync updates to its copy of the zone.
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync The solution to this is to add 2147483647 (2^31-1) to the
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync number, reload the zone and make sure all slaves have updated to
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync the new zone serial number, then reset the number to what you want
ab79888f2d6b4c61dd9ed587aec2bd70dcc17966vboxsync it to be, and reload the zone again.
