A list of Windows protocol erratum is maintained at https://msdn.microsoft.com/en-us/library/dn781093.aspx. The issue was discovered during a Samba Interoperability event last September.

Well, what about 3.3.5.9.14 Handling the SVHDX_OPEN_DEVICE_CONTEXT
Create Context:
<snip>
"""
If IsSharedVHDSupported is FALSE, the server MUST fail the request with
STATUS_INVALID_DEVICE_REQUEST.
"""
I think this is why Samba is returning INVALID_DEVICE_REQUEST.
(pressing on this point b/c I prefer to back a modification by
documentation or at least "dochelp says so...")
Thanks,
Uri.
