3139N/A The best solution to solving installation and
3139N/A configuration issues is to take preventative measures by setting
3139N/A up logging files beforehand. The log files provide a
3139N/A source of hints and information that can be used to figure out
3139N/A what went wrong and how to fix the problem.

3139N/A Zone serial numbers are just numbers — they aren't date
3139N/A related. A lot of people set them to a number that represents a
3139N/A date, usually of the form YYYYMMDDRR. A number of people
3139N/A tested these numbers for Y2K compliance and set the number
3139N/A to the year 2000 to see if it would work. They then tried to restore
3139N/A the old serial number. This caused problems because serial
3139N/A numbers are used to indicate that a zone has been updated. If the
3139N/A serial number on the slave server is lower than the serial number
3139N/A on the master, the slave server will attempt to update its copy of
3139N/A Setting the serial number to a lower number on the master
3139N/A server than the slave server means that the slave will not perform
3139N/A updates to its copy of the zone.
3139N/A The solution to this is to add 2147483647 (2^31-1) to the
3139N/A number, reload the zone and make sure all slaves have updated to
3139N/A the new zone serial number, then reset the number to what you want
3139N/A it to be, and reload the zone again.
