Using the Viewer : Preemption : Preemption of a Local User/Remote Administrator by a Remote Administrator

Preemption of a Local User/Remote Administrator by a Remote Administrator
If an administrator attempts to access a server that is being accessed by the local user or by another remote administrator with equal privileges, the currently connected user can accept or reject the preemption request. A message appears asking the connected local user or remote administrator whether they want to accept the preemption request. If the preemption request is rejected a message appears informing the remote administrator that their request has been rejected and that they cannot access the server.
NOTE:
NOTE:
In scenarios where a preemption request can be rejected, the Session Preemption Request dialog box will appear. This dialog allows you to accept the preemption request by clicking the Accept button or to reject the preemption request by clicking the Reject button or by closing the dialog box.
