Log off Windows user without closing VNC connection?

[Martin Valley]

Some parts of this message have been removed. Learn more about Nabble's security policy.

I have installed TightVNC (ver 1.3.9) on several computers with VNCServer having been installed as a service.

 

There are occasions when I want to log-off as the Windows user (so that no user is logged-in).

 

However, on some of the computers, when I log-off, any connections from VNC clients are closed and the clients can no longer connect to the server until the Windows user logs in again. But on other computers, the client are NOT disconnected. In fact, a client user can log-off and log back on on the server machine (which is the behaviour I want).

 

It appears to me that both VNCServer installations are the same. What is causing this different behavior? What do I have to do/setup/specify to enable this on all installations?

 

Thanks.

        it seems that on the working PCs the VNC is installed as a "service program" and on
the others not working PCs the VNC is working like a standard program.

I have the same issue, and the machines in question Tight VNC is installed
as a service. I lose connection switching from the administrator account to
a user account. I run the kids account as a user in XP.

It is normal if user set the 'session password', eg you connect as a
system password, then switch to a particular user that have set their
password and VNC (correctly) disconnects you and force to relogin with
correct (user) credential.

I've added to my logon script:

        REG delete HKEY_CURRENT_USER\Software\ORL\WinVNC3 /va /f

to cleanup user data at every login, clearly would be better to add a
master switch 'prevent users to set a user password' or something like
this...

Thanks for the responses.

I got it working "properly" again by:
 1. un-installing VNC completely.
 2. going into the register and deleting each & every entry with "VNC" in
it.
 3. re-booting the computer.
 4. installing VNC again (as a service, of course)

After this, everything works as it should.

I agree, it would be better to have some kind of a switch on the properties
page to control this feature.

Most likely, this is due to differences between default settings and
user settings on that machine. When no user is logged in, TightVNC
server uses default settings. When some user logs in, the settings of
that user will be used instead. If you cannot connect to the machine
when nobody is logged in, that probably means that the default settings
do not allow that (e.g. passwords not set or different TCP port is
specified etc.).
