First follow the online tutorial, allow remote access under Windows, then set up folder sharing, and then log in through smb on the Mac, the window for entering the user name and password always shakes, and it has been unable to connect. At this time, use another Windows on the same LAN The machines can be accessed remotely, but the Mac just cannot. As shown below.
1. Enter "secpol.msc" in Run to start the local security settings, and then select Local Policies->Security Options-->Network Security LAN Manager Authentication Level, the default option of "Security Settings" is "Not Defined". Change to "Send LM and NTMLM Response (&)" or "Send LM and NTMLM - use NTLMv2 session security if negotiated"
2. If it doesn’t work, look at the local security settings you just opened, the option Local Policies –> Security Options –> Guest Account Status is disabled, open it to view. The general meaning is that if this option is turned off, the SMB service cannot be used, because the SMB service is used by UNIX for sharing, so turn it on.
3. If it still doesn't work, in the security options, set the network access: sharing and security model of local accounts to "classic".
4. Turn off the public network firewall.
