    Hello, I am testing a T-Kernel based CIFS / SMB Server application with my Windows 10 Pro PC. That is, I am using my Windows 10 Pro PC as SMB Client. I could successfully communicate with SMB1 / SMB2. However, I don't know how to test with SMB3. Please suggest if I need to do some specific configuration in my Windows 10 Pro PC or if I need to check something etc.

    Thanks in advance.

    Hi Dibyajyoti,

    SMB3 supported by all versions/editions of Windows 10.

    Refer to this Microsoft document for detailed information:

    How to detect, enable and disable SMBv1, SMBv2, and SMBv3 in Windows

    https://docs.microsoft.com/en-us/windows-server/storage/file-server/troubleshoot/detect-enable-and-disable-smbv1-v2-v3

    SMB v2/v3 Protocol (only disables SMB v2/v3 Server)

    Enable:

    Set-SmbServerConfiguration –EnableSMB2Protocol $true

    Thanks a lot for your quick response. I have done all the necessary steps, as mentioned in the referred URL.

    I have checked from the PowerShell that SMB2/3 is enabled [with the following command]

            Get-SmbServerConfiguration | Select EnableSMB2Protocol

    However, I observed that SMB3 dialect is not being advertised in the SMB header of the SMB Negotiate Request Packet, sent by my Windows 10 Pro PC [SMB Client]. It advertises only upto SMB2 dialects. 

    However, I expect the following dialects to be listed in the dialect field also, that indicates support of SMB3 family:

    Dialect: 0x0300; 0x0302; 0x0311

    Please advise, if I am missing anything?

    Best Regards,

    Dibyajyoti
