Microsoft has introduced significant changes to SMB shares with the rollout of Windows 11 version 24H2, primarily enhancing security protocols. SMB shares now require SMB signing, and guest access has been disabled for most editions of Windows 11, necessitating a username and password for connection. These changes aim to address security risks associated with unauthorized data access. Users with Network-Attached Storage (NAS) setups may face accessibility issues due to these modifications. To regain access, users should enable SMB signing on their NAS and disable guest access. If necessary, users can disable security protections using Windows PowerShell, but this is not recommended.
