The error message you are encountering indicates that your organization's security policies are blocking unauthenticated guest access to shared folders. To resolve this issue, you can enable insecure guest logons on your computer. Here are two methods to do that:
Method 1: Using Registry Editor
- Open Registry Editor.
- Navigate to
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\LanmanWorkstation. If the key doesn't exist, create it. - Right-click on LanmanWorkstation, select New > DWORD (32-bit) Value, and name it AllowInsecureGuestAuth.
- Double-click it, set the Value data to 1, and press Enter.
Method 2: Using Local Group Policy Editor
- Go to Start and search for gpedit.msc, then press Enter.
- Navigate to Computer Configuration > Administrative templates > Network > Lanman Workstation.
- Double-click Enable insecure guest logons, select Enabled, and press Enter.
After making these changes, you should be able to access the shared folder without encountering the security policy error.
