Search Windows Server, February 22nd, 2023
SMB 3 (Server Message Block 3.0) is a protocol that provides a way for a computer's client applications to read and write to files from a server in a computer network. SMB 3.1.1 is the latest version.
SMB 3 is built in for Windows 8, 10, and 11 as well as Windows Server 2012, 2016, and 2022. Other devices may also share files using SMB 3, such as network-attached storage (NAS) devices, printer/scanners or macOS clients. Some Microsoft technologies use SMB 3 to serve files to clients, such as Active Directory Group Policy, Windows System center and printer sharing. Some services use SMB to store and access their data files, such as Hyper-V and Microsoft SQL Server.
