Answer 3

The above is correct. I am trying to shadow a thin client (Wyse 3040) using what you have above. The RDP settings you have above have been tried several times, with some suggesting that you move it to small then large. The MSTSC commands do not have any effect on height/width/span/fullscreen . I will post a pic if needed, but what you have stated is correct

Answer 4

Condition 2 - I have found that the settings on the think client resolution size have a effect on this. But the window should still size from the commands of the mstsc
I know that you can shadow the thin clients from the WMS (Wyse Management system) - this might be a reason it cant resize? The windows appear to be the same size

Answer 5

If I adjust the screen resolution on the thin client to something like 1360 x 720 it appears to fill the entire RDP screen, but again, I would like to see the mtsc commands work.
