After the recommendation of my TAM, I updated my vrops module view to the latest one (guess it is 6.5.x) to resolve this problem, but the results still differs from vROPS and helpDesk inside Horizon View.
And yes we are using non persistent desktops because the main client usage is by default office, browser, email, nothing special. On a security perspective it is really helpful not store any data on the client itself, because after logoff the client is deleted and a new one is going to be created. User specified data (roaming) are redirected to a share by gpo.
With this mechnism we avoid a lot of attack vectors from outside by browsing or more simple: cloaked clients by time and usage.
Hope that was not too weird especiallly with my limited english language skills :-)
