Michel,

>Since yesterday, a XP PC cannot reboot. I can have it reboot in Safe Mode but as soon as I try to have it in regular mode, it just dislays nothing after the first XP blue startup screen. Then, I checked the Event Viewer. In the Application log, I have this message:
>
>The COM+ event system detected a bad return code during its internal processing. HRESULT was 8007043C from line 44 of d:\nt\com\com1x\src\events\tier1\eventsystemobj.cpp. Please contact Microsoft Product Service...
>
>Anyone knows how to recover that?
