Now my problem is, how to get it to show the dialog which lets me assign resources such as a drive on this computer to show up as available in the remote session.
I personally haven't done that, so not sure where this is done from the UI (/dialog). Is it done in the "Local Resources" tab on the dialog?
Anyway, irrespective of how it's done from the UI, it's got a command line equivalent. For the command prompt, these configurations are specified through a config file. The mstsc accepts the config file as a
parameter. The configurations equivalents to their UI counter parts are listed
here. So going by what you mentioned, i think you are after the "redirectdrives:i" option. So the config file (blah.rdp) would look like:
and then the mstsc command would be:
I haven't really played with the config files for mstsc (and don't have a Windows system right now, to try this), so not sure if this is exactly what you are looking for
