Follow these steps in order and test access to \\WDMYCLOUDMIRROR after each major step.
- Verify the device and network
- Make sure the WD My Cloud Mirror is powered on and connected to the same router/network as the Windows PC.
- Confirm the PC is on the same network (same router/Wi‑Fi SSID) and that internet and local network access work.
- Try accessing by IP address
- In File Explorer, enter
\\<device-IP>(for example,\\192.168.1.50) in the address bar instead of\\WDMYCLOUDMIRROR. - If this works but the name does not, the issue is name resolution rather than connectivity.
- In File Explorer, enter
- Turn on network discovery and file sharing (Windows 11/10)
- Open Settings → in the Find a setting box type manage advanced sharing settings → select Manage advanced sharing settings.
- Under Private networks, turn on Network discovery and File and printer sharing.
- Under All Networks, temporarily turn off Password protected sharing to test.
- Ensure the network is set to Private
- In Settings, go to Network & Internet → select the active connection (Wi‑Fi or Ethernet).
- Make sure the network profile is set to Private.
- Start required sharing services
- Press Windows key + R, type
services.msc, press Enter. - For each of these services, right‑click → Properties → set Startup type to Automatic and start them if stopped:
- Function Discovery Provider Host
- Function Discovery Resource Publication
- SSDP Discovery
- UPnP Device Host
- Press Windows key + R, type
- Check SMB/guest access policies (if share uses guest/anonymous access)
- If the NAS is configured for guest (no‑password) access and Windows shows messages about guest access being blocked, enable insecure guest logons:
- Registry method (Home editions):
- Open Registry Editor (
regedit). - Go to
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\LanmanWorkstation(create the key if it does not exist). - Create a DWORD (32‑bit) Value named
AllowInsecureGuestAuthand set Value data to1.
- Open Registry Editor (
- Or Local Group Policy (Pro/Enterprise):
- Run
gpedit.msc. - Go to Computer Configuration → Administrative Templates → Network → Lanman Workstation.
- Open Enable insecure guest logons, set to Enabled.
- Run
- Registry method (Home editions):
- Restart the PC and try
\\WDMYCLOUDMIRRORagain.
- If the NAS is configured for guest (no‑password) access and Windows shows messages about guest access being blocked, enable insecure guest logons:
- Check SMB protocol and security negotiation
- Some NAS devices use older SMB/security settings that newer Windows builds reject.
- Open Windows PowerShell (Admin) and run:
Set-SmbClientConfiguration -RequireSecuritySignature $false Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" RequireSecureNegotiate -Value 0 -Force - Restart the PC and test access.
- If still failing with 0x80070035
- Try again by IP (
\\<device-IP>). - If IP also fails, temporarily disable third‑party firewall/antivirus and test.
- If IP works but name does not, add a static entry for
WDMYCLOUDMIRRORin your router’s DNS or the Windowshostsfile (advanced) so the name resolves correctly.
- Try again by IP (
If the device is reachable by IP and the above Windows settings are applied, 0x80070035 (network path not found) should be resolved in most home‑network scenarios.
