Have you set up a packet handler on the RCX before sending this? I would
guess that if there isn't one, you'll run into something like TCP's
"connection refused", which might be what you're seeing. Otherwise, I
assume that other LNP stuff (e.g. dll) works under the same conditions? If
neither of those are in the right direction, can you code up a very simple
test case that fails, and either send it to me or post it somewhere?
Looking at the whole thing might help.
