I have a problem with vnc.
I have 4 PCs at home (3 with Windows XP / 7 with a vnc viewer and with the penultimate version of debian is already integrated with vnc server) and a router.
The PC with no monitor or keyboard is debian (used only for repository/p2p), so I use vnc viewer to access it from Windows PC.
Yesterday I finished the installation and tested vnc vnc viewer from any PC with W7 and everything worked properly.
Today, however, is not vnc: gives me the error “Connection refused (10061)

I think the problem is caused by the fact that yesterday (when the connection is successful) I logged onto the PC debian, but now I’m trying to connect to the system before login.
Obviously, since the pc debian is no keyboard and mouse is essential that the login is done via vnc from your windows machines.
