Larry,
	As default Hobbit does use ares resolver library. Maybe it's
having some trouble who your nslookup doesn't showup.

	You can play with two bbtest-net options, to help give a litle
more info on this issues...

-------<cut from man bbtest-net>----------------
       --no-ares
              Disable  the  ARES resolver built into bbtest-net. This makes bbtest-net resolve hostnames using your system resolver function. You should only use
              this as a last resort if bbtest-net cannot resolve the hostnames you use in the normal way (via DNS or /etc/hosts). One reason for using this would
              be if you need to resolve hostnames via NIS/NIS+ (a.k.a. Yellow Pages).
              The  system  resolver function does not provide a mechanism for controlling timeouts of the hostname lookups, so if your DNS or NIS server is down,
              bbtest-net can take a very long time to run. The --dns-timeout option is effectively disabled when using this option.

       --dnslog=FILENAME
              Log failed hostname lookups to the file FILENAME. FILENAME should be a full pathname.
-------<cut from man bbtest-net>----------------


	And you can play a litle with:
	cd ~server/bin
	"./bbcmd bbtest-net --debug ppd2.wcm.ess.usda.gov" 
	
	-wm
