></H1
><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
