Access to shared storage from Windows VM in workspace?

Describe the bug
I have a workspace with several Windows and Linux VMs. The Linux VMs are able to see the shared storage at /fileshares/vm-shared-storage, but the Windows machines cannot see it.

I have enabled public network sharing/discovery, that doesn't help any.

Steps to reproduce

1. Create a workspace with shared storage
2. Create a Windows VM in that workspace, with access to the shared storage enabled.
3. Fire up a remote desktop on the VM, look for the shared storage, fail to find it.

Screenshots showing the process of opening network drives on new VM:

On entering the VM for the first time, I get this prompt. I select 'Yes'

Then I open File Explorer, and go to the Network tab. It scans, finds nothing interesting, and shows the message about file sharing being off. I turn it on, as shown. It rescans the network, but nothing changes.

Start by reproducing the reported workspace setup with shared storage and a Windows VM, comparing it with the working Linux VM access. No files or tests are named; investigate how shared storage access is enabled for Windows VMs and verify that the share is discoverable from File Explorer when the issue is resolved.
