[jcifs] NTLM HTTP and Windows 2003 Problems

I'm having trouble getting jcifs to perform NTLM HTTP authentication
against a Windows 2003 domain.

If I configure the web.xml to not perform preauthentication by only
setting "jcifs.smb.client.domain" parameter, everything works fine for a
single user, but a second user connecting to the site will usually get
an "Unverifiable signature" failure.  

I read the note in the documentation that suggested performing
preauthentication by setting the "jcifs.smb.client.username" and
"jcifs.smb.client.password" properties.  However, in this configuration,
the client browser just hangs and an error is thrown in the server log.

Any suggestions?  Thanks in advance.

Here's the error in the log file:

INFO: Starting Coyote HTTP/1.1 on port 8080
session established ok with MYDOMAIN<1C>/X.X.X.X
byteCount=48 but readBytesWireFormat returned 34
java.net.SocketTimeoutException: Receive timed out
        at java.net.PlainDatagramSocketImpl.receive(Native Method)
        at java.net.DatagramSocket.receive(DatagramSocket.java:711)
        at java.lang.Thread.run(Thread.java:534)

Also, here's the relevant jcifs section from my web.xml file:


My environment:
Web Server:  Red Hat Linux ES v3, Apache Tomcat 4.1.29 using mod_jk2
Client: MS IE 6
