Hyper-V Windows 10 Pro virtual machine networking...

Question

We have a Windows 10 Professional virtual machine (VM) running under Hyper-V. This VM needs to share one of its drive folders to other computers connected to the host's network. These computers can ping the VM with the network share, however when trying to map the share to them, we always get a network share unavailable or not found error....

How can we troubleshoot this? I'm only used to VMWare so I'm not familiar with Hyper-V.

Does the Hyper-V host also have some firewall which can stop the folder sharing protocol? Do the Hyper-V network interfaces have different profiles (internal / public etc) ??

Thanks a lot for help and hints on this issue....

Best regards Tor

Answer 1

Have you looked at the Windows Firewall for the required SMB ports?

Answer 2

You mean the FW of the VM sharing the folder? Yes we have checked that and they are 'open'....

Thanks for the tip.

Answer 3

Hi,

Network shares should work in exactly the same way within Hyper-V as they do in a physical network.

It's possible that the network requests to the VM are being blocked by Windows Defender's firewall. Please update the firewall configuration to stop filtering packages on the Hyper-V virtual adapter's LAN.

I hope this answers your question.

Thanks.
