However, the 1.2.5 NtlmHttpFilter still fails when the first DC in the 
list returned from WINS is bad (stack trace at the end). Apparently, it 
does *not* proceed to the other DCs in the list, as suggested above.

We have a customer that wants resilience against a DC failure.  How can 
I provide that to him using jcifs?
