Windows NT 4.0 includes a feature that produces memory dumps when the system or an application crashes. This feature is useful for debugging purposes, but malicious users can exploit it to learn application-specific security data (e.g., passwords). How can I turn off memory dump file creation in NT 4.0?
You can turn off memory dumps in the System Properties Control Panel applet by clearing the Write debugging information to check box on the Startup/Shutdown tab. This check box is selected by default on an NT 4.0 installation.
