Here's the environment...
Server 2012 Hyper-V Host :
VM1 = Domain Controller
VM2 = Remote Desktop Server (RDS)
Both VMs are accessed via static IP through the Hyper-V host's Virtual Switch.
After each reboot of the Hyper-V host the Domain Controller's NIC comes up fine but the RDS's NIC doesn't. The RDS NIC "looses" its Default Gateway...the field is blank in the NIC's Network Connections > IPv4 Settings...and the only way to recover it is to disable / enable the NIC.
I've written a powershell script to disable > enable the NIC but before testing wanted to table this issue here to see if anyone has any idea of how to fix without implementing a hack / work around?
Look forward to feedback!
