Hi @ronfint ---- Thank you for the follow up and taking the time to answer my questions. Both are appreciated!
Moving forward, can you please verify the following for me:
Please provide the make and model Netgear switch that is being used in your setup.
Can you confirm if jumbo frames are disabled on the Synology NAS.
In your initial report to us you mentioned the following:
I do this via itunes on a separate computer. All was well, but this morning half of my albums were missing and Roon was rescanning.
The watch folder you have mounted in ROON, is this same location that is being accessed by your itunes library? If you are indeed using Roon + iTunes together, can you confirm if your iTunes XML is in the same location as the media or is it in a separate location?
