Is it Possible to take Screen Capture of remote machine when session is not active?

[rahuroy 0]

I have written scripts for installation on remote machine and whenever there are failures i am capturing screenshot.I am invoking au3 scripts using psexec but if machine session is not active then screeen capture coming as blank , for successful screen capture , is it mandatory for session to be active?

How to achieve taking of screenshots of remote machine when session is not active?

snippet of code i am using

$title = WinGetTitle("", "")

$text = WinGetText("", "")

$hGUI=WinGetHandle($title)

$file=@ScriptDir & "\ "& $testcase &" "& @MON & @MDAY & @YEAR & @HOUR & @MIN & @SEC & ".jpg"

_ScreenCapture_CaptureWnd ($file,$hGUI,0, 0, 300, 400, 0)

Thanks.
