Hey Robert, Isabelle, This usually happens when the client has an old agent but the NAC Server has the same agent with a wrong version number when the agent was uploaded manually. For example, end user is using 4.1.3.0 and the NAC Server is also having a 4.1.3.0 agent but when someone uploads it, they tell the system that it is a 4.1.3.1 agent. This will cause the loop. This is one possibility.
To find out the actual cause, I will need the agent log.

We opened a TAC case but haven't heard back about a work-around. I've since done some testing with running the 4.5 agent for Mac (with the 4.1.2.1 server) and it seems to work fine. I know that agent/server combination is supported, but I'm not sure what the licensing restrictions might be on distributing the 4.5 client if you are still licensed for 4.1. ---- Isabelle Graham Information Security American University Robert J.
