What should I do if port 445 is closed for win sharing

If port 445 is closed, Windows sharing will not be able to be used normally, so we will replace Windows sharing with cloud box permission sharing.

Compared with Windows sharing, CloudBox private cloud disk sharing is more secure. Based on the private cloud deployment, CloudBox encrypts and stores files in a centralized manner, and does not use high-risk ports such as 445, so that the Linux system avoids most virus attacks. In addition, the scientific organizational structure and rich permission settings make CloudBox more advantageous than Windows sharing.
