Fix Network error code 0x800704F8 in Windows 11

Fix Network error code 0x800704F8 in Windows 11

The operating system treats such requests as unsafe and prevents them. Below are five practical fixes to resolve this issue so you can access shared resources without interruption.

Fix 1: Adjust Microsoft Network Client Settings

Windows may require digitally signed communication for network connections, which older devices may not support.

1. Open Local Security Policy by searching for secpol.msc.

2. Go to Local Policies and click on Security Options.

3. Locate Microsoft network client: Digitally sign communications (always) and … (if server agrees).

4. Set both options to Disabled.

5. Restart and test the network connection again.

Fix 2: Check Network Discovery and Sharing Settings

Sharing must be enabled correctly for devices to appear on a local network.

1. Press Windows+R and type control /name Microsoft.NetworkAndSharingCenter and press Enter.

2. Click Network and Sharing Center and then Change advanced sharing settings.

3. Turn on Network discovery and File and printer sharing.

4. Ensure Password protected sharing is turned off if you are on a trusted home network.

Fix 3: Uninstall Problematic Updates

Occasionally, recent Windows updates may introduce stricter SMB policies.

1. Go to Settings and then Windows Update. Then, click on Update history and then Uninstall updates.

2. Find and uninstall recent security updates that may have caused the issue.

3. Restart your PC and test the share access again.

Fix 4: Create Matching Accounts and Correct Permissions

If guest access is blocked, ensure that valid credentials and permissions are in place.

1. Create a user account on both the source and target PC with the same username and password.

2. In File Explorer, right-click the shared folder, choose Properties, then Sharing and then Advanced Sharing, then set permissions to allow access for those accounts.

3. Try reconnecting using those credentials.

Quick Tips

1. Switch your network profile to Private for home or trusted networks.

2. Ensure both devices are on the same subnet and network.

3. Temporarily disable third-party firewalls or security suites while testing.
