I have developed a VI which employs FTP to upload data files created by another application
embedded on a FieldPoint, not altogether unlike the "Redundant Datalogger" example VI found
in the NI Developer Zone. Unlike that example, I am not employing DataSockets, Citadel
database functionality or any other DSC functionality which I know or suspect does not work
in a deployed application without the DSC Run-Time Engine.
This VI works fine when I run it in the LabVIEW Development System (Full + RT + DSC), but
when I deploy the VI as a standalone application FTP (at least) appears to quit working.
I don't have the specific error code -- my VI re-interprets FTP errors to a novice-
friendly "check the LAN connection and/or FieldPoint power" warning and I will have to
modify the code to extract better diagnostics. I will also not be able to probe further
until I can get back to the fieldpoint, which is happily running its little app in a little
one-room water plant in the mountains. Meanwhile, is there something more fundamental (and
obvious to the veterans) which I am overlooking?
This application employs DSC security features and I have deployed it bundled with the
associated DSC files per the DSC manual instructions. All of that is apparently working fine;
the stand-alone just won't FTP to the fieldpoint while the development copy will.

P.S. This VI also employs TCP to continuously communicate control and status info with the
fieldpoint, but the VI gives up on the link when FTP fails and never tries to open the TCP
path.
