problem with zone transfer

[Chris Boyd]

Every few days we are having problems with local address not resolving. It seems to coincide with a zone transfer in the logs. 
Also how do you stop it from doing a zone transfer anyway...as we don't really need to as the file rarely changes? 

named[1341]: transfer of 'usit.ie/IN' from 82.195.14
6.192#53: failed while receiving responses: REFUSED
Jan 24 06:30:14 usit-hq-s02 named[1341]: transfer of 'usit.ie/IN' from 82.195.14
6.192#53: end of transfer

It attempts this every 6 hours but only stops resolving every few days so I'm not sure what's going on there. 
Anyway to get it to start resolving again you have to incriment the serial # in the respective zone file. 

$TTL 3D
@                       IN      SOA     usit-hq-s02.usit.ie. admin.usit.ie. (
                                28              ; Serial
                                10800           ; Refresh
                                3600            ; Retry
                                604800          ; Expire
                                86400 )         ; Minimum TTL
;

named.conf:

zone "usit.ie" in {
        type slave;
        file "usit.zone";
        allow-query {any;};
        masters { 82.195.146.192;};
        also-notify { 10.133.1.230; };
        notify no;
};
