SECJ0305I: The role-based authorization check failed for admin-authz operation
I did some goggling and found this tech note from IBM that recommends "restart(ing) the deployment manager, node agents, and servers." This resolved the original issue where the node agent showed as not running but when I tried to restart the node agent service to show what I had done to a peer I got the same error but the node agent status never changed from running in the Deployment manager : ( I will post a follow up to this issue at a later date (when it is worked out).
