Lenovo laptop no longer connecting to VPN

Having issues with a Lenovo X1 carbon running windows 8.1 and the built in windows VPN connection. Connection was working just fine four days ago and can see in event viewer where it connected, but now all of a sudden when trying to connect there is a 720 error. No changes have been made to the operating environment or networking environment. Two other windows 7 machines can connect so there is not a problem with the VPN tunnel setup Windows 2008 r2 server side.

Try deleting the VPN connection profile on the laptop, restarting, and then remaking the VPN profile.

1stITMAN I found that one already. When I ran it and then rebooted it and let windows install the drivers on its own, I was then getting 806 errors. Which I know cannot be right because I was able to connect using my Windows 7 machine inside my same network and to the same VPN server. Also I tried opening that protocol in the firewall and rebooted and tried again and same 806 error. Then tried dropping firewall all together and rebooted and tried again and still 806 error.

And you deleted the VPN profile as suggested. What happened when you did that?

By profile you mean connection? Or the actual ras file in appdata?

PPTP VPN has a connection profile just like dial-up. You should see it the Network Connections properties (where you see network connections). That is the one I am talking about.

Do you have other computers connecting to UNO?  (The Windows 7 machines above?).

I wonder if recent Windows updates changed things. There were some large updates yesterday. Can you restore to a prior point to see if this might be the issue?

Yes other machines are connecting just fine. And yep also already tried a restore. Restored to a day when it was working and still got same error

You may need to consider a Windows 8 Refresh. This is done from Action Center. You will have to install that did not come with Windows 8, but your data will remain intact.

Windows * Refresh did not work. May need to backup and do a fresh install. Any other advice to prevent a complete wipe?

I use VPN all the time from XP to Windows 8.1 inclusive. I never had any difficulty with VPN on Windows 8.1 but I use NCP for VPN which is utterly reliable.

If you cannot make it work then, yes, a fresh install is now probably indicated after all you have done.

Proceeding with a fresh install and starting from scratch

@jvillareal78  - Thank you for the update. VPN is buried deep into networking and so sometimes this is the only way.
