6a3b299491bf7f9ba09b943b7238b170111b69ccnd>The best solution to solving installation and
6a3b299491bf7f9ba09b943b7238b170111b69ccnd configuration issues is to take preventative measures by setting
6a3b299491bf7f9ba09b943b7238b170111b69ccnd up logging files beforehand. The log files provide a
6a3b299491bf7f9ba09b943b7238b170111b69ccnd source of hints and information that can be used to figure out

6c4c113ce85934b11c9e78399e1bb8ec7a568af9nd>Zone serial numbers are just numbers-they aren't date
81ef3d132c8f335006465f297c42319f8734825dnd related. A lot of people set them to a number that represents a
81ef3d132c8f335006465f297c42319f8734825dnd date, usually of the form YYYYMMDDRR. A number of people have been
81ef3d132c8f335006465f297c42319f8734825dnd testing these numbers for Y2K compliance and have set the number
925932040ee7871b6a2418edc3b4b6f4378bbe2and to the year 2000 to see if it will work. They then try to restore
925932040ee7871b6a2418edc3b4b6f4378bbe2and the old serial number. This will cause problems because serial
925932040ee7871b6a2418edc3b4b6f4378bbe2and numbers are used to indicate that a zone has been updated. If the
73291de2e17c97d3549f2f8aa085ca43d27e108and serial number on the slave server is lower than the serial number
73291de2e17c97d3549f2f8aa085ca43d27e108and on the master, the slave server will attempt to update its copy of
73291de2e17c97d3549f2f8aa085ca43d27e108and the zone.</P
3caed8f01e7d67f3ad5d47cb28bb4e43131652fdjerenkrantz>Setting the serial number to a lower number on the master
3caed8f01e7d67f3ad5d47cb28bb4e43131652fdjerenkrantz server than the slave server means that the slave will not perform
3caed8f01e7d67f3ad5d47cb28bb4e43131652fdjerenkrantz updates to its copy of the zone.</P
36f2369ee230c310fed3b600e9e99cf5770804a3wrowe>The solution to this is to add 2147483647 (2^31-1) to the
3caed8f01e7d67f3ad5d47cb28bb4e43131652fdjerenkrantz number, reload the zone and make sure all slaves have updated to
e127d82e8afc2f885fe2183b68d4a110580d21dfjwoolley the new zone serial number, then reset the number to what you want
e127d82e8afc2f885fe2183b68d4a110580d21dfjwoolley it to be, and reload the zone again.</P
