My windows 8.1 enterprise is configured like this:

Physical Intel NIC is using Hyper-V Extensible Virtual Switch

Virtual Hyper-V Ethernet adapter is configured with a static IP so that I can RDC in

The VMs running on this box also have static IP's.

The ReadyNAS' firmware is up to date.

The host and VMs all have internet access and proper network access, I can even ping and SSH the NAS that holds the shares I'm trying to connect to.

I can see the ReadyNAS Pro under Network>Storage, if I double-click it I get "Error 0x80004002:No such interface supported"

When I try and add a share as a network location I'm told that "The folder you entered does not appear to be valid.  Please choose another."

When I try to map a network drive to a share I'm prompted for credentials, I enter them, the window just reappears asking me to login again.



I've tried enabling Jumbo Packets.

I've reinstalled "File and Printer Sharing for Microsoft Networks"

I've edited the registry entries using

powershell.exe Set-SmbClientConfiguration -RequireSecuritySignature $true

and

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" RequireSecureNegotiate -Value 0 -Force

I've configured the SMB service with these commands:

sc config lanmanworkstation depend= bowser/mrxsmb10/nsi

sc config mrxsmb20 start= disabled

I've deleted and reinstalled both adapters.

I'm really at a loss, any suggestions?

I was having the same "Error 0x80004002: No such interface supported" problem and could not find a copy of the v4.1.8 firmware online but reverting to 4.1.12 seems to have solved the problem for me.
