So I'm running into an issue with a 5.2 agent install (r245). The agent install and registers to the MC without an issue. The issue is that the agent is not polling every 10 minutes like it is supposed to. I placed the same policy on my workstation and I can poll without a problem. The system will still report back to the MC if necessary (if an event logs), and once it does the host shows as active again. But then goes inactive as the polling is failing. I'm looking for details on how the agent should be polling (I think it's UDP, but what port?) and if there's any debugs I can do on the client side to find the issue. We've removed the XP SP2 firewall so it should not be blocked on the workstation. Thanks in advance!
