Windows Server 2019 VPN Error 8007042a After KB4480116

Solution 1:

So I ended up installing server 2016 to solve my problems. Even after I uninstalled the update, the vpn service mysteriously stop working again. Rebooting the server sometimes fixed it but I can not trust this to keep working. I also had a problem where DHCP was not working either. From other forums I read, lots of people where having the same DHCP problem. Looks like server 2019 is not ready for prime time. I am going to revisit this in 6 months to see if microsoft fixed the problem.

Solution 2:

Same identical problem. my workaround is to remove RRAS, restart server, reinstall RRAS and reconfigure VPN access.

It works,.....until next update that make me do the above steps again...…….

No comment about MS behavior about this problem...….

Solution 3:

I found temporary solution. NPS service (Network Policy Server) blocks starting RRAS. If you stop NPS, you can start RRAS and after that you can start NPS. If you don't use NPS you can probably disable it. I've changed service settings to start RRAS Automatic and NPS Automatic (Delayed start), but I can't test it now on production server. At least you can start it manually if you are in local network and you don't have to reinstall RRAS to get it work. It was big mistake to install 2019 to the small company. It's the only server so there isn't any older Windows Server.
