Batching requests is a perfectly legitimate thing to do. According to
the spec certain fields that would be returned in the first message are
supposed to be used in the "AndX" message (e.g. the UID). I would rather
find out why NetApp is cranky about this but to get around the problem
for now (if that is the problem) try:

  useBatching = false

I'll take a closer look at the log traces when I get to work.

Chris,

Did you ever test jCIFS against NetApp at the interop lab?
