Step 2. Hit the Run as administrator option under the Windows PowerShell section.

Step 3. In the command line window, type the following command and press Enter to turn off the SMB signing requirement:

Set-SmbClientConfiguration -RequireSecuritySignature $false

Step 4. Type Y to confirm the operation.

Step 5. Input the following command and press Enter to disable guest fallback:

Set-SmbClientConfiguration -EnableInsecureGuestLogons $true

Step 6. Input Y to confirm.
