Scripting: awk reg. exp.

Hi!
I'm trying to write a little script to automate some changes to
/etc/qconfig: changing certain host names. I've decided to use awk even
though (or perhaps "because") I'm not very familiar with it.

So far, I've come up with:
{sub(/host = old_name/,"host = new_name");print}
...and that works fine, except that it will also make changes to entries
which have been commented out, which I would prefer to avoid.

Is there some way of constructing the command so that it does not select
those lines which have been commented out? Remember: /etc/qconfig uses an
asterisk as a comment-character, which is damn stupid!
