[jcifs] Requirements on the NT Domain Controller for Authentication

I have implemented authentication for arbitrary credentials according to
the FAQ at:


It has worked well for me with my network's Domain Controller for weeks,
but failed with a "connection refused" io exception for a couple of
hours the other day. Although authentication failed, I was able to
'ping' the Domain Controller's IP address. My assumption is that my IT
department may have been changing something on the Domain Controller
during that time, but I don't know what might have changed or why it
affected me. (I know nothing of NT domain controllers or security

I'm hoping someone on this list can answer the following questions:

1. What are the requirements on the NT Domain Controller for this
implementation to work?

2. How do I verify that my domain controller satisfies these

Thanks for any help you can provide.
