Hi

I'm running RealVNC 3.3.7 server on Win98 (Not SE) and connecting thru a loopback 
connection on an encrypted and locked down Zebedee tunnel.  Firewall settings also 
block 
access from outside to all normal VNC and Zebedee ports.  Access is only thru a highly 
obscure port into Zebedee.
Zebedee is set to use secure public/private keys to verify at both ends that the other 
computer 
is known and 256 bit encyption is used.  In short without being totally paranoid its 
fairly secure 
- certainly very much more secure than VNC can do on its own.

On the VNC server Registry settings:

LoopbackOnly = 1
AuthRequired = 0

are set along with a null password.

So far so good - works really nicely :-)

Now, I want to stop accidental changes at the server end so I set:

Registry setting:

AllowEditClients = 0

Now on starting VNC server I get an error box:

WinVNC Error
WARNING:  This machine has been preconfigured to allow un-authenticated connections to 
be accepted and to prevent users from enabling authentication.
[OK]

I fully understand and accept that:
(AuthRequired = 0) & (Password = null) & (AllowEditClients = 0)
would normally, to say the least, have some security implications.

However, so far as I can see,
(LoopbackOnly = 1) & (a secure tunnel)
addresses those security implications.

The problem is that the error box blocks VNC starting without manual intervention at 
the 
remote machine and:
Logon VNC>Reconfigure Remote>Reboot>Re-Logon VNC>more configuration
doesn't work.

So after all that waffle, and in the hope that I have not sent you not all to sleep,  
I have 2 
questions:

1.      Is there a way to circumvent the Error Box
2.      If not, could the test be changed in a future version of VNC so that the box 
does not 
appear if LoopbackOnly = 1.

I know that this is just a very minor niggle in really great software.  However I do 
believe a 
solution would help to improve security whilst reducing fragility of settings :-)

Best Wishes
