I've done suggestions I've read online that say disable Network Location Awareness . When they hang I can reboot and unplug the network lead and it goes right on just fine. This is related to ESET as this just starting happening when I rolled them out. It's very sporadic and only when the systems are restarted. I wasn't aware there was a new client so I'm trying that right now. I'll be sending this out some today and the rest this weekend. I'm really hoping going from 4.0.314 to 4.0.417 will fix the issue.
