c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff The best solution to solving installation and
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff configuration issues is to take preventative measures by setting
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff up logging files beforehand. The log files provide a
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff source of hints and information that can be used to figure out
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff what went wrong and how to fix the problem.

c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff Zone serial numbers are just numbers-they aren't date
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff related. A lot of people set them to a number that represents a
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff date, usually of the form YYYYMMDDRR. A number of people have been
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff testing these numbers for Y2K compliance and have set the number
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff to the year 2000 to see if it will work. They then try to restore
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff the old serial number. This will cause problems because serial
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff numbers are used to indicate that a zone has been updated. If the
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff serial number on the slave server is lower than the serial number
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff on the master, the slave server will attempt to update its copy of
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff Setting the serial number to a lower number on the master
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff server than the slave server means that the slave will not perform
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff updates to its copy of the zone.
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff The solution to this is to add 2147483647 (2^31-1) to the
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff number, reload the zone and make sure all slaves have updated to
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff the new zone serial number, then reset the number to what you want
c6d4c11c9b36a9645bee58eb43cbf7c674e2028cJeff Conniff it to be, and reload the zone again.
