There is a good doc on the NT DC location process here and how to hack
it here:

There seems to be a form of DC location called H-node that will
broadcast if WINS fails to give it some DCs.  The 30 secs is probably
the default timeout.  I saw a situation like this today on a machine
that had a bogus WINS address for our primary domain.

Then there is M-node, which broadcasts first but does not wait for the
full timeout.  In all there are about 5 different location mechanisms
mentioned in that article.
