Reese - are you just running the command ./scriptutil or are you ref'ing a specific script? If you're running scriptutil from the appserver against the sup2sol9serv1 agent, I believe the command should read like this:
scriptutil -h sup2sol9serv1.int.bladelogic.com -s net_no_user_rhost
However, I have only run this on 6.2 and not 6.2.3. I don't know if there's a difference.
Reese, to where did you copy scriptutil? It should be run locally, with the scripts that you are trying to run copied. If you mistyped, then okay, but if not - that could be the problem.
