268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein>The best solution to solving installation and
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein configuration issues is to take preventative measures by setting
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein up logging files beforehand. The log files provide a
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein source of hints and information that can be used to figure out
b272d38cc5d24f64c0647a9afb340c21c4b9aaf7Evan Hunt what went wrong and how to fix the problem.</P

0b062f4990db5cc6db2fe3398926f71b92a67407Brian Wellington>Zone serial numbers are just numbers-they aren't date
0b062f4990db5cc6db2fe3398926f71b92a67407Brian Wellington related. A lot of people set them to a number that represents a
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein date, usually of the form YYYYMMDDRR. A number of people have been
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein testing these numbers for Y2K compliance and have set the number
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein to the year 2000 to see if it will work. They then try to restore
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein the old serial number. This will cause problems because serial
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein numbers are used to indicate that a zone has been updated. If the
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein serial number on the slave server is lower than the serial number
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein on the master, the slave server will attempt to update its copy of
bf45f72ed319628eebce60c368177320943d001fMark Andrews the zone.</P
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein>Setting the serial number to a lower number on the master
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein server than the slave server means that the slave will not perform
0b062f4990db5cc6db2fe3398926f71b92a67407Brian Wellington updates to its copy of the zone.</P
0b062f4990db5cc6db2fe3398926f71b92a67407Brian Wellington>The solution to this is to add 2147483647 (2^31-1) to the
0b062f4990db5cc6db2fe3398926f71b92a67407Brian Wellington number, reload the zone and make sure all slaves have updated to
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein the new zone serial number, then reset the number to what you want
268a4475065fe6a8cd7cc707820982cf5e98f430Rob Austein it to be, and reload the zone again.</P
