How to support SMB3 in Windows 10 Pro? (2024)

Question

_{Tuesday, July 14, 2020 3:13 PM}

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

/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

Regards

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
