Strang thing happen to day when found some zone still declare in named.conf but the db file for that zone didn’t exist anymore. Off course on log I will found some error messege indicate non existing db file for a zone.

Actually I am doing checking the DNS server for some problem, one domain registered always suffer ‘lost the name server’. When I use DNS tool from I always got the DNS server found but can’t be contacted.

; <<>> DiG 9.3.2 <<>> @localhost A
; (2 servers found)

Then I remove the miss configuration in named.conf of the DNS server , reload the named and then magicly the domain query was very smooth to query . . . is it related with non existing db file on DNS Server ?
