...well, it isn't "correct", it's just the way Microsoft did it.

My personal opinion is that NetBIOS names should *never* be mapped into 
the DNS.  The two name spaces are separate and have separate meaning.

...but no one ever listens to me.  ;)

WORKGROUP<00> is a group name, and WINS will store all group names
*except* those of type <1C> as having an IP of 255.255.255.255.  This is
bad behavior, but it's what MS chose to do.

I'm not sure how wins-hook is set up.  If it's simply an option to update 
the DNS then yes, you'd want to filter out the 255.255.255.255 entries.  
You might be able to configure the DNS server to reject those.
