My co-worker and I are both running a web application on Eclipse 3.1, jdk 1.4.2, Tomcat 4.1.31 and we're both taking our source from CVS so I'm fairly confident that our configurations are identical.  On my machine, JCIFS runs like a champ, here are my settings from web.xml:

Wow, you must be an "old school" JCIFS user. The jcifs.util.log property
is no longer used. See jcifs.util.loglevel. Also you might want to review
the latest docs. Some things have changed over the years.

Are there multiple network interfaces are on the machine? If so you
might need to set the laddr property so that jcifs is communicating on
the right one.

Technically jcifs.http.domainController should be an IP.

Look at the networking setup on the machines. I bet it has something to
do with that.
