    Hi @Russell Matt ,

    Thanks for your feedback.

    You can use Powershell command below to check if SMBv3 enabled in windows server 2012 R2

    Get-SmbServerConfiguration | Select EnableSMB2Protocol

    To check if Encryption is enabled on server level, run below command:

    Get-SmbServerConfiguration | Select EncryptData

    To check if Encryption is enabled for individual file share, run below command:

    Get-SmbShare -Name <sharename> | Select EncryptData

    For more details regarding SMB security enhancements, please refer to the following article:

    Hope my answer will help you.

    Hi @Russell Matt ,

    You can follow the guide provided in the official Microsoft documentation over here:

    How to detect, enable and disable SMBv1, SMBv2, and SMBv3 in Windows
    https://learn.microsoft.com/en-us/windows-server/storage/file-server/troubleshoot/detect-enable-and-disable-smbv1-v2-v3

    To enable SMBv2 and SMBv3 on a Windows Server 2012 R2 server, run the following PowerShell command:

    Set-SmbServerConfiguration -EnableSMB2Protocol $True

    Hi,

    Thanks for posting in Q&A platform.

    Before we go further, may I know if your goal is to enable SMB3 on particular machine(s). If there is any misunderstanding. Please feel free to let me know.

    As a quick answer, to enable SMB2 and SMB3 on Windows 8, Windows 8.1, Windows 10 and Windows Server 2012 and later versions, you can use below Powershell command:

    Set-SmbServerConfiguration –EnableSMB2Protocol $true

    Please kindly notice that SMB3 will be enabled together with SMB2. When SMB client and server do SMB negotiation, only the highest version of SMB Dialect will be chosen.

    And you must restart the computer after you make these changes.

    Hope my answer will help you!

    Best Regards,
    Sunny
