On top of that, if the problem is with your Windows image, these commands will fix it too. This process needs to be executed in Safe Mode.

3. Change the Status of Network Services to Running

It’s pretty clear that you won’t be able to connect to the internet if some of your network services are stopped in the background. As a result, Windows will display the 0x800704b3 error. Therefore, running the network dependencies in the background through the Task Manager is recommended.

Here’s how to do it:

  1. Press the Windows key and type cmd in the search bar
  2. Open the Command Prompt as administrator.
  3. Now run the following commands one by one and connect to your network again:

net start eventsystem
net start browser
net start wzcsvc

4. Start the TCP/IP NetBIOS Helper

This service allows users to print, share files, and log on to their network. In the event that this service is not running or the value data is wrongly entered, the NetBIOS Helper won’t run, and the user won’t be able to connect to the network. First, try to start the TCP/IP NetBIOS Helper service. If that shows an error, then move on to change its value data to 2.

Here’s how to carry out the whole process.

  1. Select Computer Management after right-clicking on the Start button.
    Running Computer Management in WIndows 10
    Computer Management option in Windows 10
  2. Expand the Services and Applications tab and click on Services.
  3. Now scroll down and right-click on TCP/IP NetBIOS Helper and select Start.

    Computer Management Window
  4. You can encounter an error that says “The system could not find the specified path” while starting the service. If so, press the Windows key and open the command prompt as administrator.
  5. Now run the following command to change the value data in lmhosts to 2:
    reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\lmhosts" /v "start" /t REG_DWORD /d 2 /f
    Changing value data in lmhosts
    Value data changing command
  1. Check whether Windows is still showing the error or not after restarting your PC.

5. Disable SMB 1.0 Protocol

SMB is a network file-sharing protocol whose main purpose is to share access to different resources (files, printers, communication) over a network. There are three versions (SMB 1.0, 2.0, and 3.0) of the Server Message Block at the moment.

Version 1.0 is disabled by default. Therefore, if you have enabled it by mistake, your system will fail to connect to the network, and hence the 0x800704b3 error will show up in Windows.

But no worries, just follow the steps below and disable SMB Version 1.

  1. Click on the Start button and type Windows Features in the search bar.
  2. On the subsequent window, look for SMB 1.0 and uncheck the option.

  2. Now check if you can connect to the network.

6. Create a New User Account

Sometimes the problem can be with the account you are using. It could be due to corrupted system files, viruses, or malware. You can create a new admin user account and see if the issue gets fixed or not.

  1. Enter the following commands after running the command prompt as administrator:
net user "account name" /add
net localgroup administrators "account name" /add
  1. Enter the name you prefer in place of “account name
  2. Now see if the same error occurs in the new account or not.

If the error is gone, follow our guide to transferring all your data to the new account.

7. Perform an In-Place Windows Repair

This method will reinstall Windows without disturbing any files or applications on your computer. Moreover, if there are any corrupt or damaged system files, they will be repaired.
