Dynamic access control: customize the error message
The customization of the error message is done using a group policy by activating two settings, as for the publication of the central access policy, I used the Default Domain Policy, in production it is advised to dedicate a Group Policy (GPO) for these settings.
From a control, create or modify a group policy at the domain root level, right-click on it 1 and click on Modify 2.
Go to the Assistance in the event of access denied 1 folder located in Computer Configuration / Policies / Administrative Templates / System.
Open the Enable access denied assistance for all file types 1 setting by double-clicking on it.
Activate 1 the parameter then click on Apply 2 and OK 3.
Open the Customize access denied error message 1 parameter by double-clicking on it.
Activate 1 the parameter then configure the options 2. To finish click on Apply 3 and OK 4.
The settings are enabled.
Refresh group policies on the file server and clients.
You should receive a customize error message when accessing a denied file.
