Answer 3

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
