I am using VNC 4 on my Vista machine with no problem. I had to change ports on the VNC server but it worked with no problem. I had to change the port to 5920 and the java port to 5820. It was weird and no reason for the work around but it worked nonetheless, I found the answer in some blog or forum someplace but I know it does work. You just have to login using the port number so it'll look like \\192.168.1.1:5920 or http:\\192.168.1.1:5820
