Microsoft has been making several enhancements to Server Message Block (SMB) over the past couple of years. Windows 11 Home no longer ships with SMB1 due to security reasons, and the Redmond tech giant has also recently begun testing support for Network-designated Resolvers (DNR) and client encryption mandates in SMB3.x. Today, it has announced further changes to the client-server communication protocol with the rollout of the latest Windows 11 Insider build.
