You run old multi-function printers with old firmware in order to “scan to share”.
Multichannel & SMB Direct (3.0+) - aggregation of network bandwidth and fault tolerance if multiple paths are available between client and server, plus usage of modern ultra-high throughout RDMA infrastructure.Client oplock leasing model (2.02+) - limits the data transferred between the client and server, improving performance on high-latency networks and increasing SMB server scalability.Durable handles (2.02, 2.1) - allow for connection to transparently reconnect to the server if there is a temporary disconnection.Peer caching of folder and file properties (2.02+) - clients keep local copies of folders and files via BranchCache.Larger reads and writes (2.02+)- more efficient use of faster networks or higher latency WANs.When you use SMB1, you lose key performance and productivity optimizations for end users. We believe this so strongly that when we introduced Scaleout File Server, we explicitly prevented SMB1 access to those shares!Īs an owner of SMB at MS, I cannot emphasize enough how much I want everyone to stop using SMB1 Your client will happily derp away on SMB1 and share all its darkest secrets unless you required encryption on that share to prevent SMB1 in the first place. All they need to do is block SMB2+ on themselves and answer to your server’s name or IP. The nasty bit is that no matter how you secure all these things, if your clients use SMB1, then a man-in-the-middle can tell your client to ignore all the above. Signing performance increases in SMB2 and 3. HMAC SHA-256 replaces MD5 as the hashing algorithm in SMB 2.02, SMB 2.1 and AES-CMAC replaces that in SMB 3.0+.
In September of 2016, MS16-114, a security update that prevents denial of service and remote code execution. Hi folks, Ned here again and today’s topic is short and sweet: First published on TECHNET on Sep 16, 2016
