45ba3f8b55734aa2c96b6fc510919565ba70038cTimo Sirainen The best solution to solving installation and
45ba3f8b55734aa2c96b6fc510919565ba70038cTimo Sirainen configuration issues is to take preventative measures by setting
45ba3f8b55734aa2c96b6fc510919565ba70038cTimo Sirainen up logging files beforehand. The log files provide a
45ba3f8b55734aa2c96b6fc510919565ba70038cTimo Sirainen source of hints and information that can be used to figure out
45ba3f8b55734aa2c96b6fc510919565ba70038cTimo Sirainen what went wrong and how to fix the problem.

f01fe9df4240c5b15d0b1c4b485a38f7c5736781Timo Sirainen Zone serial numbers are just numbers-they aren't date
f01fe9df4240c5b15d0b1c4b485a38f7c5736781Timo Sirainen related. A lot of people set them to a number that represents a
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi date, usually of the form YYYYMMDDRR. A number of people have been
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi testing these numbers for Y2K compliance and have set the number
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi to the year 2000 to see if it will work. They then try to restore
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi the old serial number. This will cause problems because serial
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi numbers are used to indicate that a zone has been updated. If the
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi serial number on the slave server is lower than the serial number
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi on the master, the slave server will attempt to update its copy of
b78f4649c236bf4746c81c1d0e877675f0842ac8Timo Sirainen Setting the serial number to a lower number on the master
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi server than the slave server means that the slave will not perform
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi updates to its copy of the zone.
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi The solution to this is to add 2147483647 (2^31-1) to the
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi number, reload the zone and make sure all slaves have updated to
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi the new zone serial number, then reset the number to what you want
1de7b73a11afda43323410a4481d866930b1e632Aki Tuomi it to be, and reload the zone again.
