Sounds like you downloaded from an out of date mirror site.  Take a look
at  There are brief instructions
there on how to run WinVNC as a service on NT 4, which will eliminate the
screen-saver problem.

Yes and no.  _Ideally_ it would be the default but since running WinVNC as
a service requires Administrator priveliges on the machine in question,
it's not such a good default.  Being able to run it as an app to test it
before doing a proper service install seems like a good way round to do

Certainly.  Log on into an Administrator account and go to the winvnc
install directory.  Type "winvnc -install" and then "net start winvnc".
If all goes well then it should install and start running.

You should be able to just do a straight Ctrl-Alt-Del (check whether this
will reboot the solaris client first though!!!) and WinVNC will be able to
pick it up.
