A follow-up: I think I know why I had these difficulties setting the import filter up:
1) The login ID and password to access the NAS were not the same when running ConquestServer as a service with nobody logged in to the computer, compared to when using the GUI while logged in to the computer. I found that the ID and passwd can be configured for the service (of course, this setting gets lost when uninstalling/reinstalling the service via the Conquest GUI).
2) An unexpected behaviour of the ConquestServer: it seems if a patient previously was stored to MAG0, if you then resend the same patient, it keeps being stored to MAG0, even if the import filter is pointing to MAG1. Is this true, and if so, is this behaviour intentional?
