windows 跨网段访问samba you can't access this shared folder because your org

 提示错误：

　　　　　　You can\'t access this shared folder because your organization\'s security policies block unauthenticated guest access.

　　　　　　These policies help protect your PC from unsafe or malicious devices on the network.

原因：

　　因为Window10 更新安全策略，默认禁止访问无密码的Samba共享

解决：

　　在Samba中增加用户名密码配置, 并在配置文件smb.conf 中注释掉 map to guest = bad user 

          如：　　　　

　　　　# This option controls how unsuccessful authentication attempts are mapped
　　　　# to anonymous connections
　　　　#map to guest = bad user
