Title

Terminal Services is not configured to delete temporary folders. (Cat II impact)

Discussion

This setting, which is located under the Temporary Folders section of the Terminal Services configuration option, controls the deletion of the temporary folders when the session is terminated. Temporary folders should always be deleted after a session is over to prevent hard disk clutter and potential leakage of information.
