72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott>The best solution to solving installation and
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott configuration issues is to take preventative measures by setting
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott up logging files beforehand. The log files provide a
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott source of hints and information that can be used to figure out
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott what went wrong and how to fix the problem.</P

72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott>Zone serial numbers are just numbers-they aren't date
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott related. A lot of people set them to a number that represents a
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott date, usually of the form YYYYMMDDRR. A number of people have been
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott testing these numbers for Y2K compliance and have set the number
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott to the year 2000 to see if it will work. They then try to restore
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott the old serial number. This will cause problems because serial
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott numbers are used to indicate that a zone has been updated. If the
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott serial number on the slave server is lower than the serial number
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott on the master, the slave server will attempt to update its copy of

72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott server than the slave server means that the slave will not perform
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott updates to its copy of the zone.</P
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott>The solution to this is to add 2147483647 (2^31-1) to the
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott number, reload the zone and make sure all slaves have updated to
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott the new zone serial number, then reset the number to what you want
72450cb9c2ca854c6d3479832c2738196c1d3282Robert Wapshott it to be, and reload the zone again.</P
