DCOM errors, and iTunes re-launches itself

for some unknown reason, i recently started getting DCOM errors showing-up in the system event log relating to an iTunes DCOM registry entry (see below). these errors occur shortly after iTunes has been launched, even though iTunes itself is running just fine. it doesn't crash or anything, BUT when i close iTunes, the strangest thing happens... iTunes will terminate ok, but then restarts/launches itself a few seconds later! when i close it the second time, it stays shutdown at that point. kinda creepy. anyone else experiencing this strange behaviour with iTunes or the DCOM errors in the event log?
