3628e59dec497ce19ee5a166249755c861902b06Phill Cunnington>The best solution to solving installation and
3628e59dec497ce19ee5a166249755c861902b06Phill Cunnington configuration issues is to take preventative measures by setting
a093731116a8c24d49b903df7602cf586e499b45Phill Cunnington up logging files beforehand (see the sample configurations in

3718b64edcbcad3874cae9b01e00e1b64586f11bJames Phillpotts related. A lot of people set them to a number that represents a
a093731116a8c24d49b903df7602cf586e499b45Phill Cunnington date, usually of the form YYYYMMDDRR. A number of people have been
a093731116a8c24d49b903df7602cf586e499b45Phill Cunnington testing these numbers for Y2K compliance and have set the number
3718b64edcbcad3874cae9b01e00e1b64586f11bJames Phillpotts to the year 2000 to see if it will work. They then try to restore
3718b64edcbcad3874cae9b01e00e1b64586f11bJames Phillpotts the old serial number. This will cause problems because serial
3718b64edcbcad3874cae9b01e00e1b64586f11bJames Phillpotts numbers are used to indicate that a zone has been updated. If the
3718b64edcbcad3874cae9b01e00e1b64586f11bJames Phillpotts serial number on the slave server is lower than the serial number
3718b64edcbcad3874cae9b01e00e1b64586f11bJames Phillpotts on the master, the slave server will attempt to update its copy of

c9f1d3043c1f8394a35ebfd5aad3bdeb841e55dfPhill Cunnington server than the slave server means that the slave will not perform
3718b64edcbcad3874cae9b01e00e1b64586f11bJames Phillpotts updates to its copy of the zone.</P
3718b64edcbcad3874cae9b01e00e1b64586f11bJames Phillpotts>The solution to this is to add 2147483647 (2^31-1) to the
c289b3af72dda73e53e6886c920c198b779ebf37Rich Riley number, reload the zone and make sure all slaves have updated to
c289b3af72dda73e53e6886c920c198b779ebf37Rich Riley the new zone serial number, then reset the number to what you want
c289b3af72dda73e53e6886c920c198b779ebf37Rich Riley it to be, and reload the zone again.</P
