: Intel(R) PRO/1000 MT Network Connection (These static IPs are all set programmatically for automation purposes.) Also note that working machines and non-working machines are based Note that IPConfigs for non-working machines are identical to working machines except for IP address. Nothing in the event log for the affected VMs. This can be beneficial to other community members reading the thread.

Meanwhile, could you post the route table and “ ipconfig /all “ result form on of affected computer here ?įor more information please refer to the blog post below: Please check the startup type of Network Location Awareness service and make sure it has been set to automatic and started when this issue occurred.

Out of 80 or so machines, I've had to resolve 10 of these issues. (If I spin up 12 XP machines or 12 Redhat machines, I have no problems) If I spin up 12 identical Windows 2008 R2 VMs, all with static IPs, 2-4 of them on the same LAN will show 'Unidentified Network' and will not respond to pings.
