connection problem with TightVNC to Vista/Win7 systems

Hi folks,

I am assuming the problem is due to the operation systems, as the connection from any system
XP SP2, Vista SP1/2 or Win7 to a XP system works without a problem.

(in my LAN are running 3 XP SP2 machines, 1 Vista SP1 Home Premium and 1 Windows7 ultimate machines
plus 2 NAS servers, which are out of concern)

Connecting from the Win7 system to the Vista system, vice versa or from the XP systems to the Vista or
Win7 system has the following effect:
the connection dialog appears - I enter the IP address
the standard VNC authentication dialog opens: I enter the password (which has been set in the VNC server
on the machine I want to connect to) and then the dialog appears: TightVNC info: ! Connection closed.
which then obviously happens.
If I enter a wrong password, the "authentication failed" message comes and the standard VNC authentication
dialog appears again.

As this happens with the connections to the Vista/Win7 systems only, I suspect it is an operation system
issue of TightVNC.

By the way: searching the archive with "connection closed" didn't give any hit, so I assume the issue didn't occur
yet in former times.

Help, support, would be highly appreciated.

Please turn on detailed logging and show us the log file records
corresponding to the time when connection drops. To make sure the log
file is written, run WinVNC.exe from some place where you have write
permissions.

By the way, does starting TightVNC Server as administrator solve the
issue? (Start it by right-clicking the icon and choose "Run as
administrator".)

Hi Constantin,

find below the requested log:
(I made one trial to connect from a XP and a Vista SP1 box each to the Win7 box,
where the server had been manually started (as administrator).
I also tried the reverse thing from Win7 to Vista after having started the server on
the Vista box manually - at no avail
In all cases on the client side there comes the request for authentication and after entering the
password a window keeps on appearing saying "connection closed".

So the "Run as administrator" option didn't bring any visible result.

regards
Rainer

Unfortunately, the log does not include information about any incoming
connections. It seems like nobody connected to the server while writing
this part of the log.
