Windows RasClient error 789

A few computers at our company are unable to connect to the built-in VPN that's setup on every machine.

In the Event Viewer, they receive a RasClient error with error code 789.

I've tried:

  1. Updating the computer, using Windows updates & Dell Command Updates.
  2. Removing the WAN miniports
  3. Restarting any service that has to do with remote desktop, IPSeC, L2TP, etc.
  4. Removing the VPN completely & re-installing

I've seen this happen on both Windows 11 & Windows 10 machines. I know the VPN is setup correctly since I'm able to connect to it as well as a majority of other users.

The only recent fix I could find for this was someone saying they just reset the entire computer & then it started working.

Has anyone else dealt with this issue without having to reinstall the OS.

    Hello,

     

    Thank you for posting in Q&A forum.

    This issue is most likely caused by the firewall block.

    Please kindly check if there's any windows firewall or antivirus running on the windows client and blocking the VPN traffic.

    By test this issue, you can temporarily disable the firewall/antivirus and check if this issue still persists.

    Hope this answer can help you well.

     

    Best regards，
