PDR Access Control
PDR Access Control is a Windows NT service that prevents one application
from crashing another user’s application by mistake. Though largely
transparent to users, the service prevents applications from accidentally
reloading the video processor while in use, essentially providing a controlled
gateway to the processor. Applications attempting to load different video
processor code than what is currently running are denied access and terminated;
however, applications attempting to load the same code are given access to
proceed.
The c:\profile\profile.log file tracks all messages from the video processor. The
state of the video processor is periodically checked. If the processor does not
respond, an administrator alert is generated. The event is logged to the Windows
NT Event log. The Event log can be viewed with the Event Viewer application.
PDR Access Control is automatically installed and started as part of the
installation process and is restarted every time the system is rebooted. This
procedure is provided in the unlikely event that you need to start the service
manually.
