- You establish a client session by using Windows 2000 Terminal Services.
- You try to establish a VPN connection by using Layer Two Tunneling Protocol (L2TP) from the Terminal server to connect to a Windows 2000 Server-based computer that is configured as a VPN server.
Note Microsoft does not support or recommend the use of a preshared key for IKE authentication on remote access L2TP/IPSec client connections. However, Windows 2000 is compliant with IKE Request for Comments (RFC) 2409.
- Add the ProhibitIpSec registry value to both Windows 2000 Server-based endpoint computers, and then restart both computers.
- Manually configure an IPSec policy on both the Windows 2000 Server-based computers before you try to establish an L2TP/IPSec connection between them through a Terminal Services client session.
