Drone Factory folder doesn't exist

I’m trying to configure NZBDrone to work with SABnzbd (0.7.16). I specified a legal directory for the Drone Factory folder, but ND repeatedly reports that it doesn’t exist:

13-12-10 21:13:48.9|Warn|DownloadedEpisodesImportService|Drone Factory folder [c:\DS213\Downloads\complete\SABnzbd] doesn’t exist.
13-12-10 21:14:50.4|Warn|DownloadedEpisodesImportService|Drone Factory folder [c:\DS213\Downloads\complete\SABnzbd] doesn’t exist.
13-12-10 21:15:51.8|Warn|DownloadedEpisodesImportService|Drone Factory folder [c:\DS213\Downloads\complete\SABnzbd] doesn’t exist.
13-12-10 21:16:53.2|Warn|DownloadedEpisodesImportService|Drone Factory folder [c:\DS213\Downloads\complete\SABnzbd] doesn’t exist.
13-12-10 21:17:54.6|Warn|DownloadedEpisodesImportService|Drone Factory folder [c:\DS213\Downloads\complete\SABnzbd] doesn’t exist.
13-12-10 21:18:56.0|Warn|DownloadedEpisodesImportService|Drone Factory folder [c:\DS213\Downloads\complete\SABnzbd] doesn’t exist.

Any thoughts on what might be wrong? Oh yeah, this is with NZBDrone 2.0.0.992 on Win7 x64. SAB and ND are both on the same system.

Is that a mapped drive/folder? (assuming a mapped folder to a Synology DS213)
Is drone running as a service?

If the answer to both questions is yes, then it will not work: https://github.com/NzbDrone/NzbDrone/wiki/FAQ#why-cant-nzbdrone-see-my-files-on-a-remote-server - without changing the setup.

yes

and yes

I found that FAQ in between my posting and your reply, and managed to get drone working by changing the service account to a local user that had access.

I also tried using a UNC path as suggested by the first solution, but that resulted in the same error as above. I’ll poke around some more this weekend on that one since that’s how I’d prefer to have it set up (rather than requiring a specific user).

I’d suggest not running it as a service, but instead when the system starts via the Start up folder. Services don’t have proper access to mapped network drives and permissions on UNC paths may also be problematic.
