PDR Access Control

PDR Access Control is a Windows NT service in the 2.1 release 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,
typically located in the Administrative Tools group.

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 case you need to start the
service manually.
