Thanks Günter -- you nailed it -- but I still don't understand why???

	That's amazing. I've been using 'name resolve order = wins lmhosts bcast' since
2.0.2 and never run into this issue. What could have changed? Dunno, but it is
simple enough to add host back to name resolve order.

Thank you sir :p
