This guide aims to provide you with clear, actionable steps to tackle and resolve this issue effectively. By following these instructions, you will learn how to adjust settings related to network access, modify group policy configurations, and check firewall settings to regain access to shared folders within your organization’s network.

Step 1: Modify the Registry Setting

The first step in resolving this issue is to adjust a specific setting in the Windows Registry. This change can allow secure guest authentication, which might be causing access restrictions. Here are the steps to modify the registry:

  1. Press Win + R to open the Run dialog box.
  2. Type regedit and hit Enter to open the Registry Editor.
  3. Navigate to the following path: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters.
  4. Find the key named AllowSecureGuestAuth. If it does not exist, you’ll need to create it:
    • Right-click in the right pane and select New > DWORD (32-bit) Value.
    • Name the new value AllowSecureGuestAuth.
  5. Double-click on AllowSecureGuestAuth and set the value to 1.
  6. Click OK and close the Registry Editor.

Step 2: Adjust Your Network Settings

After modifying the registry settings, the next step is to ensure that your network settings are correctly configured to facilitate shared access:

  1. Open the Control Panel by searching for it in the Start menu.
  2. Select Network and Sharing Center.
  3. Click on Change advanced sharing settings on the left sidebar.
  4. Make sure that Turn on network discovery and Turn on file and printer sharing options are enabled.
  5. Scroll down to the section titled All Networks and ensure that the following options are selected:
    • Turn off password-protected sharing (if acceptable for your security policy).
    • Enable file sharing for devices that use 40- or 56-bit encryption.
  6. Click Save changes to apply your settings.

Step 3: Modify Group Policy Settings

If the issue persists, modifying the group policy settings can help resolve access restrictions:

  1. Press Win + R to open the Run dialog box again.
  2. Type gpedit.msc and press Enter to open the Group Policy Editor.
  3. Navigate to Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options.
  4. Locate the policy titled Network access: Sharing and security model for local accounts.
  5. Set this policy to Classic – local users authenticate as themselves.
  6. Close the Group Policy Editor and restart your computer for the changes to take effect.

Step 4: Check Windows Firewall Settings

The firewall settings may also block access to shared folders. Follow these steps to review and modify your firewall configuration:

  1. Open the Control Panel and select Windows Defender Firewall.
  2. On the left pane, click on Allow an app or feature through Windows Defender Firewall.
  3. Look for File and Printer Sharing and ensure both Private and Public network options are checked.
  4. If it is not listed, click on Change settings, then Allow another app… to add it.
  5. After making the necessary changes, click OK to save your settings.
