"You can’t access this shared folder because your organization’s security policies block unauthenticated guest access"

1. Open Local Group Policy Editor
2. Go to Lanman workstation
3. Change the setting of Enable insecure guest logons from Not Configured to Enabled
4. Save changes and try again.

You will need admin permission for some of these.

1] Using Group Policy Editor

 

Open the Local Group Policy Editor. You can press Win+R, type gpedit.msc, and hit the Enter button. Alternatively, you can search for the same in the Taskbar search box.

After opening the Local Group Policy Editor, navigate to this path-

Computer configuration > Administrative Templates > Network > Lanman Workstation

On your right side, you should see a setting called Enable insecure guest logons. Double-click on it, and change the setting to Not Configured to Enabled and save your change.

Now, you should not get any problems.

2] Using Registry Editor

There is one more way to enable the functionality in Windows 10, and you can use the Registry Editor to get the job done.

Before tweaking any file, it is recommended to backup all Registry files. Then, open the Registry Editor on your computer. For that, press Win+R, type regedit, and press Enter. You need to select Yes in the UAC window. After that, navigate to this path-

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

Here you need to create a key named LanmanWorkstation, only if it does not exist already. To generate the key, right-click on the Windows key and select New > Key. Following that, name it as LanmanWorkstation.

Now, select this newly created key and right-click on the right side > New > DWORD (32-bit) Value and name it AllowInsecureGuestAuth.

Set the Value data of this REG_DWORD value as 1 and save your change.
