[jcifs] Issues getting resources using "smb://" URL

[Eric Newman]

Hi Mike,

Thanks for your reply.

I did some more research and observed what you were describing.  When a
certain machine was chosen by LMB (one which has access to the network), it
would work; but when a different machine was chosen (one which did not have
access to the network), it would not work.

Do you know if I have any control (via using jcifs) over how to influence
which machine is chosen by the LMB?

Thanks,
Eric

I think you meant to use "smb://" here.

That is because the "smb://" URL queries the Local Master Browser
(LMB) for the list of domains and that machine is determined by a
non-deterministic election protocol. Meaning, the LMB can be different
each time you query for it.

0xC00000CB is "The network resource type is not correct."

This is not unusual if there are many machines on the same physical
network that are not in the same workgroup and are secured to different
degrees. A college dorm would be exactly the kind of place where each
kids PC is managed separately.
