UltraVNC

Ok, based on posting [topic=27163][/topic] I guess the answer is no. So my follow up would be if I wanted to switch from MSLOGON to VNC password authentication, would I have to uninstall all of my VNC, then re-install or is there an easier way?

I have a little older rev of UltraVNC deployed via group policy to my machines (XP Pro). I am now having to deploy Windows 7 machines in my domain and updating my UltraVNC. My question is, can I utilize both password authentication schemes?
I currently use the MSLOGON scheme and it works fine, but ...
