Hi,

I have another bizarre error:

In this instance, the host is only found if WINS is switched on, yet the 
domain name MATERNA is pingable (and resolvable) by the Windows DC.

It must be some Windows configuration issue because I've never seen this 
problem before, even when running jcfis on a machine that can not resolve 
any windows domain name (I assume the exception is being generated by 
jcifs because Windows can not negotiate the name?).
