On mine (machine #1), jcifs could correctly identify when to use the appropriate network adapter. On the other (machine #2), jcifs could not, and it would struggle to use the wireless network adapter when it could just go to the LAN -- eventually timing out or throwing a "Failed to negotiate with a suitable domain controller for ..." exception.

This actually has nothing to do with jCIFS really. If you create a
raw network socket in Java it binds whatever interface it thinks is
primary. There's no real "solution" to this because Java cannot know
what interface you intend to use.
