    This article details how to enable and disable Server Message Block (SMB) version 1 (SMBv1), SMB version 2 (SMBv2), and SMB version 3 (SMBv3) for client componentsnt and Disable SMB server.

    p>

    While weakening or removing SMBv1 may cause problems with older computers or software, SMBv1 has significant security and vulnerability, we strongly recommend that you do not use it.

    Disable SMBv3 Or Smbv2 To Resolve Issues

    We recommend leaving both SMBv2 and SMBv3 enabled, but you may find it useful to temporarily disable one for troubleshooting purposes. For more information, see How to determine if the SMB routines on the SMB server are positive or disabled. .

    In Windows 10, Windows 8.1, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, and Windows Server 2012, disabling SMBv3 disables the following features:

  • Seamless Failover: Clients reconnect to chaos nodes without interruption during maintenance or failover.
  • Scalability: concurrent access to shared data on virtual file cluster nodes
  • Multichannel: Bandwidth pooling and group failover when betweenMultiple gateways are available between client and server.
  • SMB Direct: Added support for RDMA networking for high performance with low latency and low CPU usage.
  • Encryption. Provides end-to-end encryption and prevents eavesdropping on untrusted networks.
  • Catalog Rental: Speed ​​up dental office application response times with caching
  • Performance optimizations – small changes to allow arbitrary read/write operations.
  • On Windows 7 and Windows Server 2008 R2, disabling SMBv2 disables this feature shortly after:

  • Request Composition: Allows you to send many different SMBv2 requests in a single network system request.
  • Higher reads and writes: enjoy faster networks with better connectivity
  • Caching properties of folders and files: Clients save local copies of folders and files.
  • Persistent handles: Allow Romance to transparently reconnect to the server, as if there was a temporary disconnect.
  • Improved message placement forI’m your John Hancock – HMAC SHA-256 replaces MD5 as the hashing algorithm.
  • Improved file sharing scalability – Significantly increased the number of users, shares, and open files on the web hosting server.
  • Symbolic link support
  • Client Lock Leasing Model: Limits data transfer lock between client and server, improves performance on high latency networks, and improves SMB device scalability.
  • Enhanced MTU support: for full use of 10 Gigabit Ethernet (GbE)
  • Performance improvement: clients with files open on your server can just sleep
  • Can Windows 2003 use SMB2?

    NOTE. SMB2 will still be enabled on a fresh install of PVS 7.13 (thanks Andrew Wood). SMB 1.0 (or SMB1) – used in Windows 2000, Windows XP and Windows Server 2003 R2 is probably no longer supported and you should start with SMB2 or SMB3 which has more of these types compared to its predecessor.

    SMBv2 was created in Windows Vista and Windows Server 08, and SMBv3 was introduced in Windows 8 and Windows Server 2012. For more information about SMBv2 SMBv3 and its capabilities, see the following articles:
