When Controller 1 request the exclusive mode, other machines will shift their modes as shown below:

Figure 3-5 Flow of remote control mode changes (when Controller 1 is set to the exclusive mode)

1. Controller 1 requests the exclusive mode.
2. A message dialog box appears on the agent, stating the controller's request to acquire the exclusive mode. Choosing OK will put the agent into view mode.
3. A message dialog box appears on Controller 2, stating that another controller has acquired the exclusive mode.
   

   

   Choosing OK will put Controller 2 into view mode.
   

In example (1), Controller 1 acquires the exclusive mode and the remaining controllers assume the view mode. If Controller 1 relinquishes the exclusive mode, the remaining machines will experience the following mode changes. The same changes will apply when Controller 1 severs the connection with the agent.

Figure 3-6 Flow of remote control mode changes (when Controller 1 is disconnected from the agent)

1. Controller 1 reverts to the shared mode.
2. On Controller 2, which was originally in the shared mode, a message dialog box appears stating that another controller has released the exclusive mode. However, Controller 2 remains in the view mode.
   

   

In example (1), Controller 1 acquires the exclusive mode and the remaining machines assume the view mode. If the agent presses the Ctrl + Alt + Delete keys, the other machines will experience the following mode changes.

Figure 3-7 Flow of remote control mode changes (when the agent presses the Ctrl + Alt + Delete keys)

1. On the agent, press the Ctrl + Alt + Delete keys.
2. On Controller 1, a message dialog box appears asking you whether it is OK to change the permission level to the shared mode.
   

   

   Choosing Yes will put both Controller 1 and the agent into the shared mode. (No mode changes occur if the user of Controller 1 chooses No in the dialog box.)
   
3. On Controller 2, which was originally in the shared mode, a message dialog box appears stating that another controller has released the exclusive mode. However, Controller 2 remains in the view mode.
