Hi

i recently had to replace the hard drive in my Synology NAS and on reconnecting the NAS to the Sonos I got error 900 unable to add music library. 

Both had been working flawlessly before the hard drive replacement.

thanks in advance

    Yes, you must run SMB1.

    Spent over 2 hours on the phone with Sonos support, then tried setting the min limit to SMB1 - that fixed the issue.  Wow!

      Same here - setting min limit to SMB1 did the trick. Thank you.

      Wow, enable SMBv1 for sonos. The sonos products are very good, but a security nightmare at all. Not only of the SMBv1 requirement.

          But the big question is, when will Sonos support SMBv2 or 3. SMBv1 has a number of security vulnerabilities that are widely exploited (think of Wannacry and Petya).

          I ran into an additional issue;

          After allowing SMB1 -which solved the error 900- I still got an error that ‘user name or password are incorrect’

          I’ve fixed this by allowing Enable “NTLMv1 authentification”. I found the instruction here in this article:  https://zappiti.uservoice.com/knowledgebase/articles/1975617-how-to-activate-smb-1-on-synology-nas-dsm-7

          To echo some earlier concerns: both SMB1 as NTLMv1 authentification introduce serious security flaws. Can Sonos prioritize a fix? Does anyone know where we could address this concern?
