Hello Jeni Fauzi
- Is the shared folder set up to allow anonymous or guest access? You might remove Everyone or Guests in the share folder’s permission list, then add an entry for "Authenticated Users". Make sure to grant the appropriate permissions (Read, Write, etc.).
- On the client computers, are the users accessing the shared folder using mapped network drives or by directly typing the network path in the File Explorer's address bar? When using a mapped network drive, Windows might automatically use the currently logged-in user's credentials to access the shared resource.
- Are there any saved credentials on the client computers that might be automatically used for authentication when accessing the shared folder?
- Check the security logs on the file server for any relevant authentication-related events when users access the shared folder. This might provide insight into why security prompts are not appearing.
Best regards,
