Nếu bạn bĩ lỗi này khi vào trình duyệt Internet Explozer
To help protect your security, Internet Explorer has restricted this file from showing active content?
Thì cách sửa như sau:
This security update for IE was included in SP2. I believe it's possible to disable, though I haven't tried.
In IE, go to Tools > Internet Options > Advanced tab. Check 'Allow active content to run in files on my computer'. Restart IE.
