Yes on all counts Ryan.
I did manage to get it all running together but it involved inviting the onPC station into the session from the console and then inviting the node into the session from the onPC station. Seemed pretty stable for the hour that I had it running.
Still was not able to invite the node from the console directly.
It also appeared that the network view on the console was taking a very long time to refresh, as in it would sit there for a very long time, if not indefinitely, and not show either the onPC machine or the node.
As soon as I joined the onPC station into the session, via the network window within onPC, it would immediately appear within the console's network view. Same when I added the node from the onPC machine.
I also got a lot of messages within the console activity log relating to session slots being terminated when the node would disappear from the session. If there is a way for me to extract the log I would happily send it to you.
Just seems something is a little odd since updating.
