91216cff91b34c9ff6e846dc23f248219cafe660Andreas Gustafsson configuration issues is to take preventative measures by setting
9ecb5d33470ebfb3719a1b8d56bcefdf4b27f7b2Tinderbox User up logging files beforehand. The log files provide a
0eb371ca0dab50ae3462e98794a6126198c52f4bMark Andrews source of hints and information that can be used to figure out
9ecb5d33470ebfb3719a1b8d56bcefdf4b27f7b2Tinderbox User what went wrong and how to fix the problem.</P

0e573cdd111e060e5f6c18249b5ccacbe8abe278Tinderbox User>Zone serial numbers are just numbers-they aren't date
78f3ed4bc2fcd3d270bfd599804f3b27a1db4d91Mark Andrews related. A lot of people set them to a number that represents a
fd972434c29fc1169d66594e4cc7697d33036c2bTinderbox User date, usually of the form YYYYMMDDRR. A number of people have been
e40c4e4c17d4df338e2a7db0f84d8dbb3858964cTinderbox User testing these numbers for Y2K compliance and have set the number
37d8e0a4455876fe1e4cca511076cc2c5ab9eedeTinderbox User to the year 2000 to see if it will work. They then try to restore
fd972434c29fc1169d66594e4cc7697d33036c2bTinderbox User the old serial number. This will cause problems because serial
2a31bd531072824ef252c18303859d6af7451b00Francis Dupont numbers are used to indicate that a zone has been updated. If the
e40c4e4c17d4df338e2a7db0f84d8dbb3858964cTinderbox User serial number on the slave server is lower than the serial number
dedefc0bdbb4e6e39eeb98aa2fc6883efec2ddb0Mark Andrews on the master, the slave server will attempt to update its copy of

5747235bf35e7398984fd6b4632743396895ea7aTinderbox User server than the slave server means that the slave will not perform
c651f15b30f1dae5cc2f00878fb5da5b3a35a468Mark Andrews updates to its copy of the zone.</P
a03cb08d0c4f1ca5fbc121d2f02bdffa7eb52286Mark Andrews>The solution to this is to add 2147483647 (2^31-1) to the
dedefc0bdbb4e6e39eeb98aa2fc6883efec2ddb0Mark Andrews number, reload the zone and make sure all slaves have updated to
78f3ed4bc2fcd3d270bfd599804f3b27a1db4d91Mark Andrews the new zone serial number, then reset the number to what you want
78f3ed4bc2fcd3d270bfd599804f3b27a1db4d91Mark Andrews it to be, and reload the zone again.</P
