Accessing a VNC server without using a VNC viewer

[Cristina Alapont Pastor]

   We have different VNC servers running in our environment and we would
like to be able to control them from a centralized server in an automatic
way ( with no human intervention and then with no user interface). For
instance, one of the things we would like to do from that administration
machine is to access any of the VNC servers and request it to start a
connection to a specific client. Is this possible either with any VNC code
installed in that administration server or even without  any specific VNC
code installed there?.
   Thanks for your help.
