Unable to sync between pri & sec dns servers

[Kevin Darcy]

Usually this is caused by the zone not loading properly on the master. Because the zone doesn't load properly, the master doesn't answer "authoritatively" for the zone. This then prohibits zone transfers. Look in the master's logs to see if there is a problem loading the zone. Often it's a syntax error or something illegal like an underscore in a name or "CNAME and other data".

                                                                                                                                                        - Kevin

However, the primary dns server is unable to transfer the zone files over to the secondary dns server when there are changes done to it. I did increment the serial number and the ip address were specified correctly. I've included the config files for my primary & secondary dns server. Please let me know if you sopt the problem.
