Control.exe failure

Hi,

My control.exe is present in C:\windows\system32\ (windowsXP SP2) but has absolutely

no action but a screen refresh.

I can't open my control pannel and have to run my .cpl one by one.

I have copied my sun's computer on with no more effect, the problem seems not to come from

the file itself.

Can something lock it in the registery ?

Some info on this here
