Windows 10: smb 1 to smb2 upgrade

I attached a USB 3 drive to my Linksys 7310 router, then mapped a network drive from one Win10 laptop to bulk several GB of files - no problem. When I try to map to that share with another Win 10 laptop, I get an error message that the share is using SMB 1, and SMB 2 is required. How do I upgrade or workaround?

Hello Dismasd,

To better assist you with your concern, I'd like to know the following:

• Confirm which build is currently installed on your device. To check, follow the steps below:

1. Press Windows key + R, then type in winver.
2. Click OK.

• Were there any recent changes made prior to this issue?
• It would be best if you can send me a screenshot of the said error message.

If in case that you're computer is running on Windows 10 Fall Creators Update (1709), this change in default behavior is by design and is recommended by Microsoft for security. So, to enable the access in SMB, you can follow the solution from this article:

Guest access in SMB2 disabled by default in Windows 10 Fall Creators Update and Windows Server 2016 version 1709.

In addition, you may also want to check this article regarding SMBv1 is not installed by default
in Windows 10 Fall Creators Update and Windows Server, version 1709 and later versions.

Looking forward to your response.

Regards.

SMB1 isn’t safe
When you use SMB1, you lose key protections offered by later SMB protocol versions:

• Pre-authentication Integrity (SMB 3.1.1+). Protects against security downgrade attacks.
• Secure Dialect Negotiation (SMB 3.0, 3.02). Protects against security downgrade attacks.
• Encryption (SMB 3.0+). Prevents inspection of data on the wire, MiTM attacks. In SMB 3.1.1 encryption performance
  is even better than signing!
• Insecure guest auth blocking (SMB 3.0+ on Windows 10+) . Protects against MiTM attacks.
• Better message signing (SMB 2.02+). HMAC SHA-256 replaces MD5 as the hashing algorithm in SMB 2.02,
  SMB 2.1 and AES-CMAC replaces that in SMB 3.0+. Signing performance increases in SMB2 and 3.

That's why Microsoft disabled it in 1803.
