Harjit,

VNC Enterprise & Personal Editions use asymmetric cryptography for server
authentication.

Whether or not a server will accept a connection depends upon whether
QueryConnect is set, whether the connection originates from a host allowed
by the Hosts setting, whether the viewer can support the server's allowed
security methods, and whether the user can supply the required credentials
(usually username & password).

I don't know what you mean by "will the Windows authentication take place
across the encrypted session".  Obviously the user authentication stage of
the VNC session will never be sent in the clear, regardless of whether the
session is to be encrypted.  Is that what you mean?

Regards,

Wez @ RealVNC Ltd.

It seems that first step is to authenticate the server followed by Windows
authentication. I have following questions:
 
1. Is it true that public key cryptography methodology is used for server
authentication? 
 
2. What factor will determine a server to communicate to any arbitrary
client communicating to it?
 
3. Will the windows authentication take place across the encrypted session ?
