Well I posted this in the Newbie section with now responses, I think it might have belonged here all along.
Here it is.
I have Cinnamon Linux Mint 15 desktop installed on 3 machines and I have XFCE Linux Mint 15 desktop installed on 2 machines, I have pinged each machine's IP's from all machines with no problems. Here is the problem, I'm running SSL/SSH VNC Viewer on Cinnamon Linux Mint and I can find the other 2 Cinnamon Linux Mint's, but neither of the XFCE Linux Mint's can be found. If someone can help me I would appreciate it.
Thanks in advance,
