  • It could be many things. I would troubleshoot it the same way you troubleshoot a physical machine.

    • You could have MAC address issue (same MAC assigned to more than 1 NIC or vNIC in the same environment - that happens if you clone Hyper-V hosts).
    • You could be having duplicate IP or NetBIOS names on the network.
    • It could be an outdated Hyper-V Integration Service on the guest (That typically happens if you migrate a VM from old OS version host to a newer one).
    • You could have spanning tree issue on a switch.
    • It could be related to NIC teaming on host or VM.

    Try the process of elimination, by removing as many variables as possible until you find the cause.

    What's the OS on the host and guest? How does the network physical and logical topology look like?
