Question

Open the Networking tab of the VPN connection and change the type of VPN to L2TP.
Key Takeaway: PPTP, IPSec, and IPSec over L2TP are the different tunneling protocols used in VPN. Although IPsec is the most secure, it is not natively supported by Windows. So setting up VPNs to support Windows clients involves IPsec over L2TP connectivity. Since all other users are able to connect to the VPN server, you should change the VPN type to L2TP.
