BIND debug

[Edmund]

Is there any way to show in every detail when BIND resolving
for a host outside its own domain ??

I asked this question because I've got a timeout whenever I
use my name server to resolve for a host address in another
domain and I don't know what is happening.  The problem
symptom is so strange that it only happen to one host.  If I
use the other domain name server to resolve for that host,
I've no problem.
