Unable to Access Network Shares In Windows 10

Question

I'm experimenting with Rasberry Pi5 and OpenMediaVault, I've set up a NAS with 4 X 4TB SSD drives. The SSD drives are combined in one (snapraid) pool. I have multiple laptops and desktops all on the Windows 10 operating system. The machines running Windows 10 full version have no problem accessing the network drive. But on the machines running Windows 10 Tiny 21H2 the network drive is visible but access is denied. All the machines are visible to each other and can access each other's drive. On the machines running on Windows 10 Tiny I'm logged in with a local account, not with my Microsoft account.

Answer 1

Hello

Based on the information you provided, I suggest you try the following methods on the computer that cannot access the sharing:

1. Turn on network discovery and file and printer sharing, and then turn off password-protected sharing.

Select the Start button, and then select Settings.

In the Find Settings search bar, enter "Manage advanced sharing settings", and then select "Manage advanced sharing settings" from the recommended results.

In the Advanced Sharing Settings window that appears, under Privacy, select "Turn on network discovery", and then turn on File and Printer Sharing.

Under All Networks, select "Turn off password-protected sharing".

2. Turn on SMB 1.0 /clfs file sharing support in Turn Windows features on and off.

It is recommended that you refer to the following links:

I hope the above information is helpful to you.

Hello Zunhui Han,

First of all thanks for replying, the basic steps you've mentioned are the first steps I've tried with no luck

the computers that cannot access the NAS sharing, can access each others drive, so network discovery is not the issue.

• I've checked services, all the services needed are set to automatic.
• Local Policies - Security Options is set to Send LM & NTLM-use NTLMv2 session security if negotiated.
• On the Advanced TCP/IP settings windows, “WINS” tab, NetBIOS over TCP/IP is enabled.
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing hardwareID and Store keys are deleted.
• 4(TCP/IPv4) Reliable multi-cast protocol is installed.

These are all the steps I've checked but still no luck.

Still get Error Code: 0x80070035 when I try to access the NAS drive.

I have 2 laptops and 3 desktops, they are all visible to each other and can access each other's shared drives without any problem.

With 1 laptop and 1 desktop (windrunning on ows 10 pro full version) I can access the NAS drive.

With the other laptop and 2 desktops (running on windows 10 Tiny IoT Enterprise LTSC , 21H2) is the NAS drive visible but I get the Error code 0x80070035

I hope now you've got a bit more info,

Kind regards,

Erdinç

Hi Erdinç,

Thank you for your reply. You can try to modify the registry to see if the problem can be solved. Please refer to the following:

Open the registry and navigate to the following location:Computer \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters. Add the AllowlnsecureGuestAuth item and change the value to 1.

Finally, restart the computer.

Note If you modify the registry incorrectly, you can cause serious problems. Therefore, follow these steps carefully. For additional protection, back up the registry before you modify it. For more information about how to back up and restore the registry, see How to back up and restore the registry in Windows.
