Ctrl – Alt – Del to log on to Windows?

I had to make a repair installation of Windows XP Home Ed with SP1 installed on one of my client’s PC. During the repair installation appear a message: “The procedure entry point GetIUMS could not be located
> in the dynamic link library msdart.dll”, which I be able to avoid pressing Ctrl key when cliking on OK button of the message. When Repair installation was finished, the Internet access was solve, BUT I discover that I have to press Ctrl+Alt+Del to log on on the Welcome Screen or this screen will stay there forever. Any ideas of what to do to make Windows log on automatically (like before Repair Installation) without pressing this keys?
