I have a physical hyper-v host with 1 NIC. Server 2012 installed. 3 Virtual machines all using the same virtual switch. DC and EX are server 2008, FS is server 2012. After windows updates last night I cannot ping the DC or FS from any where, but can ping out from said servers. The weird thing is that when I run a steady ping on my host to DC or FS while the VM reboots I see a ping start then stop suddenly as soon as each machine its applying computer settings. Any ideas?
