>The best solution to solving installation and

configuration issues is to take preventative measures by setting

up logging files beforehand. The log files provide a

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-they aren't date
|
|
related. A lot of people set them to a number that represents a
|
|
date, usually of the form YYYYMMDDRR. A number of people have been
|
|
testing these numbers for Y2K compliance and have set the number
|
|
to the year 2000 to see if it will work. They then try to restore
|
|
the old serial number. This will cause 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.</P
