No-password file share still requires login

Solution 1:

Make sure the "ANONYMOUS" security object is granted access. "EVERYONE" doesn't count.

You also might need to allow anonymous access within group policy. Open Group Policy Editor and navigate:

- Computer Configuration
  - Windows Settings
    - Security Settings
      - Local Policies
        - Security Options.

Change “Network access: Let Everyone permissions apply to anonymous users” to Enabled

Solution 2:

Boiled it down to this:

On the file server Give anonymouse Share and NTFS rights as needed (Read in my case)

Create GPO and apply to file server Computer - Windows - Security - Local - Security

Accounts:Guest account status - Enabled

Accounts: Rename administrator account - SomeNameOfYourChoise

Accounts: Rename Guest account - SomeNameOfYourChoise

Network access: Shares that can be accessed anonymously: YourShareName

Network access: Sharing and security model for local account from “Classic-local users authenticate as themselves” to “Guest only-local users authenticate as Guest”.
