This is an Access Violation exception which can have different causes (MDAC bad installation, third party components such as Oracle dlls which Oracle has a fix for etc...), but in the specific case I had some time ago this was due to a corrupted Windows Scripting Host engine. This was a classic ASP application and it was crashing randomly; we captured a dump with adplus (4 dumps, actually) and the stack of the faulting thread was always the same:

The call stack shows the VBScript engine is called to run the ASP page, and is crashing just after the initialization; I'm not completely sure if this stack is specific to this problem or if we would have something similar also for the other known causes (MDAC and Oracle dlls) because unfortunately I've not had the chance to review those dumps, so just keep in mind this as a possible solution and not the only one...
Anyway here we fixed the problem reinstalling the Windows Scripting Host engine for Windows 2003 (version 5.7, as I'm writing).

Had a "trappable error" on my site and found my way here throught google.
I just liked the quote of the day! :)
I'm always getting bumped when viewing Office of Secure Transportaion links, last one gave me a C0000005 bump which brought me here, what gives ?~
