Disable the [Ctrl][Alt][Del] function i

‘m currently connecting to a WINNT TSE using RDP from a Compaq T1000 (Thin Client). I need to either disable the [Ctrl][Alt][Del] function or change it. Is their any software or shareware I can use? I recently read an article on disabling hotkeys, but I tried the software (Macro) recommend and it didn’t work. Any help will be greatly appreciated. Thanks
