Greetings - this is my first post :)

I have a brand new SL 6.9 running in a virtual machine on a VMware server. Our IT folks set up Tiger VNC 1.1.0-24.el6 to work with VNC Viewer 6.0.3 on my Windows 7 workstation. It worked for a day, but then it stopped. I'm not sure what happened, but now my VNC Viewer tells me "The connection was refused by the computer".

I read different forums and tried editing '/etc/sysconfig/vncservers', etc., but the result is the same.  Being a total newbie to SL, I would really appreciate your advice!
