VPN“错误 768: 因为加密数据失败连接尝试失败”

今天要测试l2tp协议,连接vpn时老是报错—–“错误 768: 因为加密数据失败连接尝试失败”,很奇怪,在百度上没找到解决办法的VPN 768错误终于解决了,就在Google上搜索到的,看来关键时刻还要靠老外才行,国内的IT水平和氛围存在不少差距。 解决方法: “运行”“services.msc”然后在服务中启用“IPSEC services”即可,如为了方便以后经常使用L2TP IPsec VPN,则可以把该项服务设置为“自动”。 以下是原文: Error 768 corresponds to Policy mismatch between client and server. Make sure IPSec service is running on both client as well as the server. You can do this by typing this command on command prompt “sc query policyagent” if this returns “Stopped” then to start this service type “net start policyagent”.
