c9912c5eafa03fdf53e569eaf2e89d7e0932975bDavid Herrmann The best solution to solving installation and
c9912c5eafa03fdf53e569eaf2e89d7e0932975bDavid Herrmann configuration issues is to take preventative measures by setting
c9912c5eafa03fdf53e569eaf2e89d7e0932975bDavid Herrmann up logging files beforehand. The log files provide a
ec5249a27adb1ffbcd41f2c771e19c3353819456Daniel Mack source of hints and information that can be used to figure out
ec5249a27adb1ffbcd41f2c771e19c3353819456Daniel Mack what went wrong and how to fix the problem.

ec5249a27adb1ffbcd41f2c771e19c3353819456Daniel Mack Zone serial numbers are just numbers-they aren't date
ec5249a27adb1ffbcd41f2c771e19c3353819456Daniel Mack related. A lot of people set them to a number that represents a
ec5249a27adb1ffbcd41f2c771e19c3353819456Daniel Mack date, usually of the form YYYYMMDDRR. A number of people have been
e1439a1472c5f691733b8ef10e702beac2496a63David Herrmann testing these numbers for Y2K compliance and have set the number
e1439a1472c5f691733b8ef10e702beac2496a63David Herrmann to the year 2000 to see if it will work. They then try to restore
e1439a1472c5f691733b8ef10e702beac2496a63David Herrmann the old serial number. This will cause problems because serial
e1439a1472c5f691733b8ef10e702beac2496a63David Herrmann numbers are used to indicate that a zone has been updated. If the
e1439a1472c5f691733b8ef10e702beac2496a63David Herrmann serial number on the slave server is lower than the serial number
e1439a1472c5f691733b8ef10e702beac2496a63David Herrmann on the master, the slave server will attempt to update its copy of
e1439a1472c5f691733b8ef10e702beac2496a63David Herrmann Setting the serial number to a lower number on the master
e1439a1472c5f691733b8ef10e702beac2496a63David Herrmann server than the slave server means that the slave will not perform
e1439a1472c5f691733b8ef10e702beac2496a63David Herrmann updates to its copy of the zone.
11811e856b0c63439d45edc9c9834ad427e1bb6aDavid Herrmann The solution to this is to add 2147483647 (2^31-1) to the
10fa421cd2abdc2ae1a07f7c13bfaa4ee6d6de4fDavid Herrmann number, reload the zone and make sure all slaves have updated to
10fa421cd2abdc2ae1a07f7c13bfaa4ee6d6de4fDavid Herrmann the new zone serial number, then reset the number to what you want
10fa421cd2abdc2ae1a07f7c13bfaa4ee6d6de4fDavid Herrmann it to be, and reload the zone again.
