Hi George,

For some basic documentation on the installation process you can have a 
look at some of WestGrid's documentation. There is a fairly extensive 
install manual that should be up to date with respect to 2.3.

Not sure if it will solve your problems but it might help. In 
particular, you should not need to run AGNodeService explicitly on the 
display machine if you are running the VenueClient on the display 
machine, as the VenueClient starts up all of the appropriate services 
that are required to manage the node when it starts. You should just 
need to run a ServiceManager on each machine that does not run the
