Capturing screen on a remote Windows server (Windows Vista or later)

[cyril <cyr...@gm...>]

Hi all,

could anyone tell how was achieved access to all windows desktops 
without having an user logined locally or via RDP? TightNVC works almost 
like Windows RDC. The code of it is in C++ and I cannot understand it 
fully that's why I'm asking here about the main idea. The same question 
at stackoverflow.com

Thanks in advance!
