Scenario: A Citrix Administrator configures the `Auto connect client drives` user settings to map client drives within the Independent Computing Architecture (ICA) session for all published desktops. The setting is configured in a Baseline Group Policy Object (GPO) and linked to an Organizational Unit (OU) that contains all of the published desktops.
When a user launches the desktop, client drives are NOT mapped. What is a possible reason?

A. Desktops need to be rebooted to get the policy applied.
B. Loopback processing is NOT enabled.
C. gpupdate/force needs to executed on all of the machines.
D. GPO needs to be linked to the User OU.
