Windows – Allow Non-Domain Computers To Access File Share But Require Authentication

file-sharingnetwork-sharewindowswindows-server-2016

I would like to know how to setup a file share that non-domain computers can access but still be authenticated by the credentials they provide to see what folders and files they have access too (authorization).

Example

User Bob is on his personal PC and goes to \\SERVER to display the available shares in file explorer. Before shares being displayed a windows log-in prompt appears asking for credentials.

Best Answer

Make your NTFS and Share level permission at least authenticated users and remove the everyone permission groups
