Doh - that is what happens when you type under stress! SMB, connecting to my QNAP NAS.

Easiest fix would be editing it into your sources.xml file, use the kodi file manager to copy it on to your Nas and the edit it in notepad as per:

http://kodi.wiki/view/Sources.xml

And then use the file manager to copy it back in and overwrite the old one.

Overall, though, might be better to switch to nfs, if your qnap supports it.

Thanks for the answer tredman, but still cannot get it to work. Did as suggested - edited the sources.xml and copied it back to the Shield. If I now restart Kodi, indeed the user/password is still present in the sources.xml, but Kodi still has issues accessing the share. Well, sort of. If I go to the source directly via "Files", I can access my movies without any issues, even play them. This didn't work before. However, when going via Library it fails every time (get a message saying the file is missing asking if I want to remove it from the library). Also updating the Library fails. I removed all sources and started fresh, just in case, but with the same results. I turned debug mode on, and logged one Library update. This is what I see:

INFO: SMBFile->Open: Unable to open file : 'smb://serverName/**/**/**/**.mkv' (<--- Path edited)
unix_err:'d' error : 'Permission denied'

To me it looks like the library procedures don't pick up the user/password from the sources.xml even though it's there - am I wrong? If I remove the user/password from sources.xml and manually add the credentials manually via the sources GUI all works perfectly, but then I need to re-do this every time I start Kodi. Unfortunately NFS is not an option due to the way the NAS is setup and synced with another NAS - long story. SMB credentials are setup correctly on the NAS, and where from other computers within the network.

Any suggestions? Cheers!

Quick update: I decided to start from scratch and re-install everything after clearing cache and app data. Now my SMB user/pass is stored correctly, so issue solved!
