Using SMB2 with ReadyNASRND4000 NV+1 v1

Retired_Member  Enabling the SMB2 protocol does not disable the SMB1 protocol on your legacy ReadyNAS. Here is the problem that the SAMBA implementation in place is outdated, the effective high-risk vulnerabilities (not talking of the features SMB1 does not offer, like encryption, protocol signing, Jumbo Frames support, better performance over VPNs, ...) were fixed on SAMBA with newer versions and patches for legacy versions for a long time.

Good NAS vendors (sorry Marc_V  - Netgear isn't...) have made firmware builds available even for very old NAS models with SAMBA patches in place so the non-authenticated abuse of the high-risk vulnerabilities are fixed for similar age NAS models - years after the devices were end-of-sales and far beyond of firmware update services promised. This would allow to continue operations of these legacy NAS in secured private e.g. home networks today.

Further on, you need to be aware that the platform does certainly have other vulnerabilities beyond of SMB1. Last but not least, enabling SMB2 does not change the NetBIOS device discovery and name resolution which is part of the Windows 10 CIFS/SMB 1.0 feature - but here again WIndows has all the similar vulnerabilities on SMB 1.0 addressed a long time ago, too.
