You can also download and use the Enterprise version of the xvnc viewer for free, but it isn't Free Software. It's almost the same thing as the Free version, as far as I can tell, but there are a couple of little tweaks in the Enterprise version that I like. UltraVNC allows for some kinds of encryption. Can the xvnc4viewer be used with the encryption, or do you just have to run UltraVNC unencrypted? I usually use Xvnc with -localhost and then use ssh portforwarding to create an SSH tunnel to connect through, but I'm not sure of how to do that when the VNC server is running on Windows. Mike
