I wanted a Windows XP client which was not a member of the domain to have the same look and feel as the rest of the domain member clients. Part of creating this effect was to enable the Ctrl-Alt-Del to login prompt at startup.
In order to enable the Ctrl-Alt-Del prompt at startup in Windows XP you need to set or create the DWORD registry entry “DisableCAD” to 0.
Windows Registry Editor Version 5.00
See more information at Microsoft Technet.
You can download this registry file to set this for you.
