It's not done via NBPLookup; it's done by sending a special ATP request to 
a nearby bridge. I've sent sample code to darth via e-mail. The code is in 
MPW C and covers the use of the NBP calls as well as the zone lookup. If 
anyone else is interested, write me and I'll either send you a copy or 
just post the code to this group.
