نکته ای که در مورد ماژول‌های native وجود دارد این هست که این ماژول‌ها دسترسی بدون محدودیتی به منابع سروری دارند و از این رو حتما باید این نکته را دقت کنید که ماژول native شما از یک منبع مورد اعتماد دریافت شده باشد.

%windir%\system32\inetsrv\config\applicationhost.config

کسی که نیاز به دسترسی به این مسیر و انجام تغییرات دارد باید در بالاترین سطح مدیریتی سرور باشد.
