Thanks, AJR. I agree that the DEP serves a very useful purpose in protecting
the machine from the buffer overflow type attacks. It seems on my PC,
though, that I can't control it anymore. When I go through the Control
Panel, the DEP window is all grayed out with both the radio buttons
unselected. I'm not able to set DEP on or off. Earlier I was using the
command line interface using the commands: bcdedit.exe /set {current} nx
AlwaysOn OR ... AlwaysOff
Any ideas?
