17400N/A>The best solution to solving installation and
17400N/A configuration issues is to take preventative measures by setting
17400N/A up logging files beforehand. The log files provide a
17400N/A source of hints and information that can be used to figure out
17400N/A what went wrong and how to fix the problem.</P

17400N/A><P
17400N/A>Zone serial numbers are just numbers-they aren't date
17400N/A related. A lot of people set them to a number that represents a
17400N/A date, usually of the form YYYYMMDDRR. A number of people have been
17400N/A testing these numbers for Y2K compliance and have set the number
17400N/A to the year 2000 to see if it will work. They then try to restore
17400N/A the old serial number. This will cause problems because serial
17400N/A numbers are used to indicate that a zone has been updated. If the
17400N/A serial number on the slave server is lower than the serial number
17400N/A on the master, the slave server will attempt to update its copy of
17400N/A the zone.</P
17400N/A><P
17400N/A>Setting the serial number to a lower number on the master
17400N/A server than the slave server means that the slave will not perform
17400N/A updates to its copy of the zone.</P
17400N/A><P
17400N/A>The solution to this is to add 2147483647 (2^31-1) to the
17400N/A number, reload the zone and make sure all slaves have updated to
17400N/A the new zone serial number, then reset the number to what you want
17400N/A it to be, and reload the zone again.</P
