VNC and MSLOGON authentication password usage?

[redge]

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 my Internet filtering appliance has a cool feature that will initiate a record of desktop upon a rule violation using VNC, but it only works with VNC password authentication and not MSLOGON authentication.

moved from general help to MS Logon

Ok, based on posting Fall back to VNC password if MS Logon not available? 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?

You don't need to re-install the UVNC.

You may either:
1. Have somesone (having admin right) to change this setting at UltraVNC's admin setting manually, or

2. Use a script to change the file ultravnc.ini (which holding the ultravnc setting), and restart the uvnc_service.
