Seems like a crash in a system DLL. Don't know what's causing it. Doesn't seem to be madExcept's fault, if that's what you're wondering about?

Nope, I think it's very similar to what is in this thread. This environment (Server/Terminal services) and so on are similar, the thread above.

Just posted to anyone can check the call stack.

I have an idea of culprit, but when it goes to Test, don't know.

At least from older time there are reports that THttRIO is not DEP compatible.

Workaround is, of course, disable DEP all together. So far no idea how to go around this tough in safe manner.

I've no idea why it happens. FWIW, you could try to detect this specific crash and silently ignore it, but I don't know if the process will then continue to run fine or produce even more crashes.
