Data Execution Prevention (DEP) is a set of hardware and software technologies that perform additional checks on memory to help protect against malicious code exploits.  Design Manager is compatible with both hardware and software DEP as long as such is Windows Hardware Logo Compliant.

Design Manager is a very dynamic database application therefore problems with the computer’s firmware, RAID drivers and firmware and even printer drivers may be exploited.  With the advent of Windows XP SP2 and Windows 2003 SP2 some computers and servers will require BIOS firmware upgrades and/or RAID firmware upgrades for hardware RAID systems. Check to make sure all firmware patches and driver upgrades are installed.

In cases when a compatible DEP driver or firmware upgrade is not available, DEP can be disabled for any individual application.  For more information on setting/disabling DEP see:


Using Windows 2008 Server you can disable DEP by typing the following command at the command prompt:

Bcdedit /set {current or name of plex} nx AlwaysOff

Make sure this run for both plex in a windows mirror!
