NETBIOS Protocol does not work across different subnets

Hi,

in my company we have some VMs in the same Virtual Network within the same Subnet. In windows explorer of a VM we are not able to see other VMs in Network Resource panel. There is a reason why there is such a behaviour?

Thanks,

Alessandro

    In Azure-provided name resolution WINS and NetBIOS are not supported. You cannot see your VMs in Windows Explorer.

    @Tinti Alessandro

    I think if you follow the below steps, you should be able to enable communication between these services on multiple VMs/VNets.

    1. Turn on Network Access,
    2. Add an exception in Windows Firewall rules
    3. Open RPC port on NSGs on both machines
    4. For traffic between Vnets, make sure they are connected and the vnets can talk to each other.

    I hope this helps. Please let us know if you require any further assistance and we will be glad to assist further. Thank you!
