This sounds like the Filter is failing to negotiate. By default IE pops up
the Network Password Dialog whenever the server returns an error. Look at
the HTTP Filter documentation for possible reasons.

You do not set both unless you're using domain,user,pass as
preauthentication credentials. Again, see the NTLM HTTP Authentication
documentation on the jcifs website.

That's fine.

Also, you should really try to get Davenport to work with the latest
version of JCIFS if you have not already.
