We just started getting these errors on windows XP SP2 stations. I follwed the link to a resolution (enclosed) but unable to find the offending program (Quartine Private SHA Binding Class) when I go to the DCOMCONFIG utility as described.
Event Type: Error

The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID
