Hello Brubakes,
I did not see any more updates on this post so I thought I would tell you how I fixed this issue. I had tried the ITALC solutions below and was not happy with the results. While in the registry I looked the the vnc section to compare the settings. I happen to use fastpush no icons so I can see what the cherubs are doing without them knowing I am there, Under realvnc or what ever flavor you are running, look for the port number setting in the registry. Simply change that to 5100 and you will be able to connect with viewer. When you are in viewer use this format at the line.
pcname:5100 or ipaddress:5100. Gets you right in. I tweaked the registry on one system and reimaged the labs. We use steadystate from windows on some machines but started to change over to Deepfreeze.
Hope it helps and good luck.
Jack
