Hello
I recommend that you use Registry Editor to enable secure guest login, see the following steps:
- Open Registry Editor. Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\LanmanWorkstation.
Note: If the key doesn't exist, you'll need to create it. Hold down the "Windows" key (right-click), select "New" > "Key" and name the switch "LanmanWorkstation".
- Hold down the "LanmanWorkstation" key (right-click), select "New" > "DWORD (32-bit) Value" and name it "AllowInsecureGuestAuth". Double-click, set "Value Data" to "1", and press Enter.
Note If you modify the registry incorrectly, you can cause serious problems. So, follow these steps carefully. For additional protection, back up the registry before modifying it. For more information about how to back up and restore the registry, see Backing up and restoring the registry in Windows.
