Argent Defender all versions
Date
Monday, 23 March 2015
Summary
It is common for Argent Defender users to use single ‘Navigate’ statement combined with checking page error codes to determine a website is up or down
For example, following setup checks if website help.argent.com is available
This configuration works well until Windows 2008 R2
In Windows 2012, the page code cannot be detected, and web session script always returns successfully
As a result, the down website won’t be alerted
Technical Background
The issue is caused by changes in Windows OS
Argent Defender relies on DLL inject to determine the returned code of WININET APIs
The technique is disabled in Windows 2012
Argent is working on the issue to find an alternative method
Resolution
Customer can use keyword ‘TestStringExist’ to determine if the web page is loaded properly, then fire Alert accordingly
