Hi,
I have 2 physical Hyper-V servers. On them are several VMs each. Both servers have 2 physical NICs (one for external internet; one for internal private access) with static IP addresses.
The two physical servers can ping each other over their internal IPs, but I cannot ping from physical server > VM or VM > VM (whether the VMs are on the same host or different hosts).
Each physical server will host a DC (2 domain controllers > 1 domain), so obviously these have to be reachable from all locations.
Host #1 has an external NIC shared with the management OS and an internal NIC on the private NIC.
Firewalls etc all disabled. Pings that fail result in destination host unreachable or timeouts.
IPCONFIG of the host #1:
