Display a Custom URL Message When Users Try to Run a Blocked Application
Applies To: Windows 8.1, Windows Server 2012 R2, Windows Server 2012, Windows 8
This topic describes the steps for displaying a customized message to users when an AppLocker policy denies access to an application in Windows Server 2012 and Windows 8.
Using Group Policy, AppLocker can be configured to display a message with a custom URL. You can use this URL to redirect users to a support site that contains information about why the user received the error and which applications are allowed. If you do not display a custom message when an application is blocked, the default access denied message is displayed.
To complete this procedure, you must have Edit Setting permission to edit a GPO. By default, members of the Domain Admins group, the Enterprise Admins group, and the Group Policy Creator Owners group have this permission.
To display a custom URL message when users try to run a blocked application
On the Start screen, type gpmc.msc to open the Group Policy Management Console (GPMC).
Navigate to the Group Policy Object (GPO) that you want to edit.
Right-click the GPO, and then click Edit.
In the console tree under Policies\Administrative Templates\Windows Components, click Windows Explorer.
In the details pane, double-click Set a support web page link.
Click Enabled, and then type the URL of the custom Web page in the Support Web page URL box.
Click OK to apply the setting.
