Unattended access allows a technician to
connect to a remote computer when no user is present.
Technicians are often unable to resolve an issue during a single Rescue
session; the job may be too big, or the customer may need his computer. The
technician and customer could theoretically arrange a time for a second
session, but it is more practical for the technician to continue work later –
at a time more convenient for all – even when the customer is not present.
