If Stealth is not listed as an option, one of the following conditions exist:

Preemption permissions)

Preemption Mode
Preemption provides a means for users with sufficient privilege to take control of
a server from another user with lesser or equal privilege.
NOTE: All users sharing the connection that is being preempted will be warned, but
only the primary user will be able to reject the preemption (if allowed).
Table 4-3 outlines the preemption scenarios and detailed scenarios in which
preemption requests can be rejected. For information about preemption and
reserved or locked virtual media sessions, see "Session Sharing Options" on page
85.
