WINCC-000029 - Group Policies must be refreshed in the background if the user is logged on.

Information

If this setting is enabled, then Group Policy settings are not refreshed while a user is currently logged on. This could lead to instances when a user does not have the latest changes to a policy applied and is therefore operating in an insecure context.

Solution

Configure the policy value for Computer Configuration -> Administrative Templates -> System -> Group Policy -> 'Turn off background refresh of Group Policy' to 'Disabled'.
