Hello,
Based on the error message 0x000004f8 you provided, I suggest you use Registry Editor to enable insecure guest login to see if it can solve the problem. Please refer to the following steps:
- Open Registry Editor. Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\LanmanWorkstation.
Note: If the key does not exist, you 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.
