VNC access KO

[François CHAUSSON]

hello

I had a VNC access running between my own PC
(Viewer) up to a remote Internet connected PC
(Server) which was working very fluently.

The remote PC had to be replaced by a new one,
running Vista these days; I rebuilt the whole VNC
Server world into this new PC ( as a service,
port 5900 opened, access password).

This access does not work anymore; here what happens:
    * launching the connection, I get open the
small VNC Authentication panel which asks for the password
    * I key in the password, identical, needless
to say, to the one entered at install time there
    * a VNC Viewer alert box pops up immediately
saying: The connection closed unexpectedly. Do you wish to 
    * I click Yes
    * it loops ...
It seems to me that my request reaches the remote
PC since I am asked for the password.

But, obviously, the connection does not work.

Thank you in advance for your suggestions and help.

Francois
