The origional vnc on msWindows works by effectively copying the data 
from the screen(-buffer). Hence if the screen-lock is on, it is also on 
in the vnc-session...

RemoteDesktop works differently: that hooks into the msWindows windowing 
functions and effectively constructs the graphics and windows in the 
remote-desktop session in stead of on the console-hardware, even if the 
/console switch is provided so the console is captured.

Current (specially commercial) vnc implementations have more 
capabilities since they can spend money to microsoft to peek in the 
source and work more like remote-desktop. I expect microsoft licenses 
(and their fees) restrict this functionallity from getting to free versions.
