Hi All, Command.com is blocked via "Don't run specified Windows applications," and sure enough that works properly if a user tries to run the file directly. However, if they put command.com in a batch file, and then run that batch file, they can get to a command prompt. "Prevent access to the command prompt" is enabled, and as best I can tell, I've got things locked down as far as possible. Is there something I'm missing? There are a lot of sites out that that seem to indicate it's not possible to block this. Seems odd though. Thanks, James James F.
