tightvnc vs "loose" vnc

What OS would you need this for?  I cobbeled a C++ app together and used the
VNC functions vncDecryptPasswd and vncEncryptPasswd.  From this, I can view
the password of a remote machine.  I don't think this would be that big of a
problem, but I have to enumerate the HKEY_USERS registry key to find the
available users.  I haven't done much testing, but it wouldn't take that
long.

That shouldn't be a problem.  You still have to grab an encrypted value, but
you plug the pre-encrypted version into the policy template.

: I have a policy for VNC by System Management Technologies Software, but
for
: the life of me I can't find the URL where I got it from.  However, it
: dosen't have the password as an option.  The password get's encrypted
before
: it gets saved, so I don't think it can be done with a policy editor.

: One of the annoyances of VNC is what it is.
:
: The issue goes back to the fact that implementing a central password
system
: for Windows systems (or a remotely changeable one) would have required all
: sorts of (potentially unreliable) additions. So the same issue applies
: across
: the board to standard VNC versions.
:
: The one method I haven't seen explored yet - haven't even looked for it -
is
: using a policy file to reset the password.  That way you avoid having to
: manually run a REG.

: : Hi,
: :
: : Our current plan is to deploy vnc server to our client 9x computers via
a
: : login.bat installation that will install, run registry files etc.
: Currently
: : it runs via the startup programs the first time but subsequently
installs
: as
: : a service so that it's running even before the user logs in.  The reg
file
: : contains tweaks that disable the user's ability to shutdown the service
or
: : change any properties.  One of the difficulties we're having is in
: changing
: : the passwords via a reg file on a regular basis.  So far the only way
I've
: : found to do this is to use an un-locked-down installation, change the
: : password, export the regkey to a .reg file then run the .reg file on the
: : clients via the login script.  This is due to the hashing of the
password
: in
: : the key.
: :
: : This is to help our helpdesk department and techs trouble shoot desktop
: : problems.  They'll connect either via the viewer or a web browser.
: :
: : I just downloaded the tightvnc to test.  Can anyone comment on the
pro/con
: : of tightvnc in the scenario above or on how to change passwords on a
: regular
: : basis?

: : Thanks
