Problem not asking the user to allow connection using NTLM

[BullGates]

I'm using NTLM autentication, and I also use FastPush script with settings adjusted, I've activated the option to reject a connection by default after 30s if the user does not "allow" to connect (nice to preserve user privacy). Maybe I'm missing something, but I enter the remote machine without showing the prompt to the user to allow me to enter.

I don't have here all the settings, but now I could read something related to the "default" or "administrator" keys in the registry, should I put all the settings both under Default and Administrator for this to work?

With administrative rights, install UltraVNC manually and configure the options.
Then see where in the registry the options are stored.

I've already did that, i don't understand why, when I use MS Logon, it does not ask the user authorization to login, even if I have that option turned on. If i use another authentication, it behaves ok.

Here they are, i also tried with administrator and almost everything I could find using a registry spy utility.
