Did you make sure that your root and localhost zones are loaded last in the bind config.
The order matters, at least if you also use bind_DLZ.
I suggest, you try it.
Im Just thinking about this, if your . (root) zone is loaded, and its trying to lookup you company.corp domain.
It hits resolv.conf then you bind, and bind_dlz is not loaded yet, so lookup on the internet.
Its a possible option this happens, i dont know the bind9_dlz code.
And this, >> domain.corp is just an alias, not the actual domain name.
Setup a with a real zone.
But pretty im sure your problem is caused by one of these 2.
I suguest start with making sure your localhost and root zones are loaded last on named.conf.
In my Debian server the order is as followed.
include "/etc/bind/named.conf.options"; < here (withing the options line: at the bottum of the global options: tkey-gssapi-keytab "/var/lib/samba/private/dns.keytab";
include "/etc/bind/named.conf.local"; < here only one line: include "/var/lib/samba/private/named.conf";
include "/etc/bind/named.conf.default-zones"; < here are my root and localhost zones ( default bind, not in DLZ )
