Does it mean that > CAM is not listening on 8906 and it is supposed to? No, it looks like the CAM is trying to respond to the client, and it's getting an unreachable. It's a network connectivity thing. Other things. What is your discovery host on the CAM set to? What is the discover host on the "Problem" machines set to? (You can check this from properties I think. I know it's in the registry.) So the capture you posted leads towards connectivity, (BUT Might be a red herring) But the description you give, points towards a discovery host problem. It could be both. I'd follow the discovery host lead first, since you state this is only affecting new installs. Mike
