Hello there, Were currently experiencing a problem: We have Primary server running bind 9.1.3 and also the slave is running this too. However, recently we have been getting a problem when creating a subdomain on the a server only the primary DNS is having the domain.com.db updated and the salve is not. I have ran /scripts/fixndc on both machines and checked both files to check that the keys are the same and they are. I have also ran named-checkconf and it produced: the default for the 'auth-nxdomain' option is now 'no' This was on both servers. I have also tryed restart bind on both servers, attempted to re-establish the trust relationship between them and syc the dns. /scripts/dnstransfer seems to be working OK. There are no errors here. However its seems to be that the slave DNS is not updating any records. We created a DNS zone on the Slave DNS and the zonefile appeared on the PRIMARY server but NOT the SLAVE. This problem has only seemed to make its self known today when a user said that a subdomain he just created was not working. Anyone have any ideas on this? Any help / suggestions are appriciated. Thanks Craig.
