Unable to lock windows XP

[That_Sound_Guy]

So I feel like an idiot.. Failing at fixing this one

Scenario: I cant lock a Windows Xp SP2 box using Window + L and CTL+ALT +DEL brings up the task manager instead of the 6 button interrupt window.

Attempts to fix:

Attempted to add the enable registry DWORD to this location
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

Ran gpedit.msc and checked for option to disable ctl alt del/lock


Im lost now, Ive been poking around the web and i can't seem to find the right keywords to use to find anything relevent. Machine is not on a domain so no PDC to worry about.

Any ideas anyone? Halp!

Thanks
