Impossible to map MyCloudHome Public

Question

I have problems mapping the Public part of my My Cloud Home NAS to my window 11 LapTop. There are no problems from my phones or from my windows 10 LapTop.
I have searched for help and I have tried to:

• Activate SMB1
• Set the property AllowInsecureGuestAuth to 1
• Allowed anonymous access by changing some register values.

I have used a PowerShell script (from ChatGPT) which I ran as admin for this:
"""
Write-Host "== Aktiverar SMB1-protokoll..." -ForegroundColor Cyan

Enable-WindowsOptionalFeature -Online -FeatureName SMB1Protocol -NoRestart

Write-Host "== Sätter AllowInsecureGuestAuth till 1..." -ForegroundColor Cyan

$regPath = "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters"

If (-not (Test-Path $regPath)) {

New-Item -Path $regPath -Force | Out-Null

}

Set-ItemProperty -Path $regPath -Name AllowInsecureGuestAuth -Value 1 -Type DWord

Extra steg för Windows Home – aktivera anonym gästinloggning om ej via secpol

Write-Host "== Skapar extra inställning för anonym åtkomst (om secpol inte finns)..." -ForegroundColor Cyan

$anonReg = "HKLM:\SYSTEM\CurrentControlSet\Control\Lsa"

New-ItemProperty -Path $anonReg -Name "EveryoneIncludesAnonymous" -Value 1 -PropertyType DWord -Force | Out-Null

New-ItemProperty -Path $anonReg -Name "RestrictAnonymous" -Value 0 -PropertyType DWord -Force | Out-Null

"""

Then I restarted.

It still does not work:

When I try to map using the cmd command "net use Z: \<IP-to NAS>\Public" as admin I get the system error: 3227320323

I see the NAS (as "MYCLOUD-CD1H9") in the File Explorer as device in the Network. When I click it I get an error message in Swedish, in English something like:

Impossible to reach \MYCLOUD-CD1HF9

Check the spelling ...
Errorcode: 0x80070035

This works just fine on my windows 10 Laptop.

What could be wrong?

Answer 1

Dear Stefan

Windows 11 blocks insecure guest access (SMB1) by default, even if enabled manually — especially on Home editions.

✅ Solution:

1. Use My Cloud Home's official desktop app or web access — WD does NOT support direct SMB access to \Public on My Cloud Home.
2. My Cloud Home is different from My Cloud — SMB mapping is blocked by WD for security.

If you have any questions feel free to reach me.
