Slow XP Boot

I've been optimizing my XP by following service disabling guides, but something I've disabled causes my XP's boot screen to slowly fade in before it actually loads. If I restore default settings with Black Viper's reg file, it stops. Can anyone look at my list of disabled services and see which one might be causing the slow boot? Thanks.
