Shared Folder is a folder that uses virtualizations software to a share files between the connected users. It’s usually created by a local machine that wants to share its files between the uses with those who have its access credentials. Others don’t have access to its content because of the policies set by the local machine. This helps protect the shared folder content from unsafe or malicious systems on the network. You will get this message if you ignore the policies and try to access the shared folder without the right credentials.
Other reason why this error can happen on Windows 10 is mostly because of the improper installation of the SMB1 and deactivations of SMB2.
