Upgrade to Windows 10 2004 (VPN L2TP fail autoconnect)

No way, no luck.

I tried again to install 20H2, VPN with PPTP doesn't work.

Tried to install KB4592438, answer was "already installed in the system".

Windows version is 19042.685

Looked for new updates, the only one is KB4586876, a Net.Framework one.

Uninstalled all the WAN Miniport drivers, deleted the input connection, restarted the system, the WAN Miniport drivers where newly installed, I redefined the input connection, but the problem is still there.

I tries to connect VPN with PPTP again and it didn't connect, message was "network connection was interrupted with the VPN Server".

So, system downgraded again to 1909 compilation.

Any idea of help will be appreciated

Regards

How did you go with this?? I have 80 laptops to look after here and I can feel my heart sinking already.

Still same situation, I will do next try in some weeks, maybe when the January update from Microsoft will come. If anyone would have any other solution, I am ready to to try it.

Regards and a Happier New Year to everyone.

Try this.

Run regedit

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\NlaSvc\Parameters\Internet

Change the EnableActiveProbing th 0;

（Sorry my English is poor.)

在vpn登陆后，无互联网的环境下，windows会自动跳转：www.msftconnecttest.com/redirect，并且断开vpn连接。

如果vpn登陆后，可以访问互联网，windows 跳转 www.msftconnecttest.com/redirect后，vpn正常。

我遇到这个问题一年多了。一直在用ltsc版本。

但禁用  跳转后，VPN正常。

我试了下 其他版本的windows，同样解决问题。

你可以试一试。

Try this. I have solve my problem.  I have tried many time on different version, that works.

Run regedit

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\NlaSvc\Parameters\Internet

Change the EnableActiveProbing to 0;

• Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\NlaSvc\Parameters\Internet]

"EnableActiveProbing"=dword:00000000

1. After you log in with VPN, in an environment without internet, windows will automatically redirect to: www.msftconnecttest.com/redirect, and disconnect the VPN connection.
2. If the VPN can access the Internet after logging in, the VPN will be normal after the windows redirect to www.msftconnecttest.com/redirect.
3. This is why some people can log in to vpn and some people cannot log in.
4. I have encountered this problem for more than a year. I have been using the ltsc version. Yesterday, after I tried to disable the redirection, the VPN became normal. I tried other versions of windows, which also solved the problem.

you can try it.
