How do I fix Error 800 789 L2TP and setup VPN in Windows 7?

Posted on November 5, 2022

If you’re using a VPN, and get prompted with the Windows 10 VPN error 789 that states: The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer. This error pops up when your system is not properly set up to connect to an L2TP server, thus the connection attempt fails even before you establish a connection with the server.

The following procedure resolves error: 789 when configuring L2TP over IPsec on Windows 10. “Error: 789, An attempt to connect using l2tp stopped because the security layer encountered a serious processing error during initial negotiations with the host”, 1. Open suggestions from the administrative control panel tools.

Step 1: Go to Device Manager on your PC. Step 2: Expand the Network Adapters node, right-click Network Command Prompt, and select Uninstall Device. Step Three: Click Remove. Step 4: Restart your computer. You will see that the PC and Windows will automatically receive the driver for the network. Then connect to the VPN to visit when the “L2TP network attempt failed” error is resolved.

This error occurs when your plan is not properly configured to restore the L2TP server, such that the connection attempt fails before the client has even connected to the server. This is certainly also due to the bad operating system configuration of your system, as in this case Windows 10.
