Hi. Probably, no.
As is indicated on the web site for jcifs, there is no longer any 
development or support on the HTTP/NTLM filter, since a long time.
Basically, this module is broken, and will not work with any Windows 
authentication environment which uses a version of NTLM > v1.
So it cannot not work, and will never work, in any recent
Windows environment / with any recent IE version, because they all use 
NTLMv2 by default.
The fact that it works with Firefox in your case is pure luck, because 
probably Firefox defaults to NTLMv1, and your Windows domain admins have 
not forbidden it.
If you want a solution that works, hava a look at Jespa, at www.ioplex.com.
