Tried this also. Didn't work. My agents are Windows 2008. I don't believe this has anything to do with it as the Windows boxes on the same subnet as the server are getting responses back from the server. On Jan 26, 1:57 pm, Kat uncommon...@gmail.com wrote: I keep seeing these from more than one

Could it be because you have multiple source IPs? Try creating a new agent on the server and use the subnet. manage_agents, a, hostname, 192.168.1.0/24, y. Then import the new key generated and see if that helps. That would confirm source IP origination is the problem. Else, use wireshark or
