Argent Advanced Technology 3.1A-1407-A or earlier


Monday, 29 Sep 2014


System Down Rule in Argent Guardian Ultra has an option to check up/down status by connecting to the Remote Desktop service at target machine

It is not working properly for Windows versions after W2003 SP5

Argent has added code to address this Microsoft bug in Argent AT 3.1A-1410-A

Technical Background

API ‘WTSOpenServer‘ is used to connect to the Remote Desktop service of target machine

It should returns NULL if Remote Desktop service is not available

In W2003 SP5 and later, the API behavior has changed

According to Microsoft Technet, the API will return an invalid handle, it is caller’s responsibility to find if the handle is valid or not by using it in another API call

Argent has been enhanced to handle this Microsoft bug


Upgrade to Argent Advanced Technology 3.1A-1410-A or later
