I had this problem. Tracked down that if I go to Device Manager and remove all the WAN Miniport protocol versions, Scan for Hardware Changes and let Windows re-install all the Mini port drivers, It seems to be working now. Hope this helps. Had to recreate the VPN connection. Using L2TP to Meraki.
Upgrade to Windows 10 2004 (VPN L2TP fail autoconnect)
Good evening.
After upgrading to Windows 10 2004, the L2TP / IPSEC VPN using MS-CHAPv2 with the option "Automatically use my Windows log-on name and password (and domain, if any) no longer connects automatically. Note that the computer in question is in an AD domain and in the previous version it was working without problems (the connection was established with the Windows credentials.
It turns out that now, in this version, it says that the user or password is wrong and shows the dialog window for entering the password. I put the same one I use for windows login and the connection is established. I wanted this to be done automatically and, if not possible, I would like to understand technically why this is happening.
Thank you.

2020-07-20T17:02:08+00:00 I will give this a go. Its a problem during these times having to get people to come into the office and re-authenticate with the domain controller just to get them back online. Rolling back to 1909 isn't viable for us. Thanks!

Anyway, I tried what Cary described. Deleted all WAN Miniports, then deleted the VPN connection and restarted the PC. But unfortunately no change. I'm still asked for the password with my Microsoft account given. But this is not what I use for my PPTP login. I need to use a plain username and password to authenticate against a VPN service running on a NAS (which worked fine for years).
Any other idea or working solution?

2020-07-20T18:51:50+00:00 But I'm not even using my Windows credentials. How can I force VPN (PPTP) to use the credentials that I have stored in the dialog while setting up the connection? Or where in the credentials manager can I find the credentials that VPN shall use?
