To continue, running "nbtstat -a host" shows two entries of type <00>, a
"unique" entry for the hostname and a "group" entry for the domain.  I can
connect to several other boxes just fine, and the common thread seems to be
that all working hosts have a <20> entry (running the file sharing service).
Is this a jCIFS limitation?  Is nbtstat doing something different to
successfully connect to the hosts without sharing enabled?
