difficulty with rescanning to include newly added music

[DavidHB]

It does look as though a full rescan would be advisable, but I agree that you need to fix the other problems first.

As regards the file paths, I too have had this problem, but I can only be of limited help because I don't have a Synology NAS. I can't check this, but I would expect that File Station shows the path. If you then check the path for your original, correctly indexed library, as shown in File Station, and compare that with the way in which the same path is represented in MinimServer properties, this should give you an indication as to how the path of the new library should be represented.

My rather simplistic approach with my NAS is to have a single path to a single music library, and make sure that everything I want to index is in that folder. If you can move your new folders into the original library (using File Station) and then rebuild both the MinimServer and iTunes indexes, that might be the best way to solve the problem.

I hope this enough to get you started.
