Does the "Isilon" server support NTLMv2?
If not you must set jcifs.lmCompatibility = 0 and
jcifs.smb.client.useExtendedSecurity = false to force JCIFS 1.3 to use
NTLMv1 as it did in 1.2.
If the server really does not support NTLMv2, then you really should
figure out how to upgrade.
If this isn't the problem, there are other things we can try ...
