L2TP VNP 拨号报错789

VPN连接的时候碰到“错误789：L2TP 连接尝试失败,因为安全层在与远程计算机进行初始协商时遇到处理错误”

设置都是正确的，原来在WINXP下需要对注册表修改下。

在HKEY_LOCAL_MACHINE＼SYSTEM＼CurrentControlSet
＼Services＼RasMan＼Parameters
下新建一个Dword名字是ProhibitIPSec，值为1
ProhibitIPSec＂=dword:00000001＂

然后重新启动计算机就可以了。

 

---------

By default, the native L2TP client in Windows 2000/XP is enabled with encryption. That is the default L2TP connection from Windows 2000 native client, that is L2TP over IPSec. To override this default behavior, we need to edit the registry key ProhibitIPSec.
1. Login to Windows 2000 as administrator.
2. Execute regedit to access the Windows 2000/XP registry.

3. Navigate to the following:
LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/RasMan/Parameters/
4.ccreate one: Select Edit > New > DWORD, then enter ProhibitIPSec on the new registry key.
5. Change the registry key value to 1.
