I have a hyper-v server that connects to an OmniOS SAN using MPIO. Whenever a storage network card changes configuration or is disconnected, Windows Firewall gets confused and acts like the primary network is Public instead of Domain and the machine becomes unavailable via RDP. A reboot fixes this but next time a storage connection goes down, it gets freaked and the same thing happens.
Some notes about my configuration:
Some notes about my configuration:
- The hyper-v server has 4x 10G network ports from 2 separate cards.
- 1 card has 1x port dedicated to a hyper-v switch and not shared with the host OS. The other port serves the OS and connects it to the LAN. The LAN port has a local static IP set on it.
- The 2nd card has both ports dedicated to iSCSI. The only protocols running on the card are IPv4 and QOS. Client for MS Networks etc. are unchecked.
- Binding order is set so all the iSCSI ports are at the bottom of the list.
- Power management is configured to not allow the OS to turn off the NICs.
- The domain controller is virtual and runs on this same hyper-v server.
