I have 2 W7 hosts (may be others, I haven't checked yet) that are on the network, and can ping the domain controller. They can also ping each other. Yet when I'm on the server, the ping request times out when I attempt to contact their hostnames or IP addresses.
I know it seems like it's not a big deal, but I think that it's a symptom of something else, because the AV management console (also hosted on the DC) cannot reach those IP addresses to push out the AV client.
Any thoughts?
