About this tag
SMB 3.1.1 is the latest dialect of the Server Message Block protocol, introduced with Windows 10 and Windows Server 2016. It offers mandatory signing, pre-authentication integrity, and enhanced encryption for secure file sharing. On WindowsForum.com, users discuss real-world deployment issues, such as intermittent SMB 3.1.1 connection failures on Windows Server 2019 after installing KB5065428, which adds SMB auditing.
