My two cents for what it is worth.
Remote Desktop Client:
- more responsive
- screen updates more reliable
- also links resources drives, printers audio and smart cards
- cannot connect to console (however, with correct client and W2003
server you can !)
- line stays busy (updating) even if window closed
- cannot talk to *nix
- some applications don't like the sandbox they are in (usually not a
problem in console mode)
VNC (4.0 free version/Window to windows):
- can connect to console even on older systems
- can talk to *nix and many others
- high cpu usage on server
- memory hungry on server with large desktops
- screen updates not always reliable
- viewer supports Windows specific keys badly
- bad (irratic) behaviour on Windows 2003/XP (fast user switching
My current choice is Remote Desktop client unless I really need access
to the console. I also find it very usefull on my Linux servers to keep
X desktops open even when I need to shutdown the laptop.
In general VNC is suitable for administration work but to slow for
production work. I must say that Ultra VNC does a better job there with
the mirror display device driver approach. With Ultra VNC responsiveness
is almost comparable with Remote Desktop.
When it comes to production work, I recently used it a lot to do
benchmarks and tests on Windows Server 2003 with Mercury Interactive
LoadRunner installed on a Windows 2000 server, I prefer Remote Desktop
because it works smoother and hardly ever misses a screen update.
And to be honest, where I before was a VNC promotor I'm currently
shifting more and more towards Remote Desktop.
