What Servelt container are you using? Which version of jCIFS are you using? Some Servlet
containers have a problem with NTLM HTTP authentication because the session must be
maintained for the exchange of the challenge and password hashes.
If you would really like to get to the bottom of what's happening quickly, get a packet
capture with NetMon, Ethereal, or tcpdump:
# tcpdump -w out.pcap -s 0 'port 139 || port 137'

A program should be written to model the concepts of the task it
performs rather than the physical world or a process because this
maximizes the potential for it to be applied to tasks that are
conceptually similar and, more important, to tasks that have not
yet been conceived.
