vpn problem - 2 (ipsec)

Hello to all! :slight_smile:

I read this article http://wiki.mikrotik.com/wiki/MikroTik_RouterOS_and_Windows_XP_IPSec/L2TP
and done all described steps. From Windows XP I get following error:
“error 768 - the connection attempt failed because of failure to encrypt data.”

Any ideas? :open_mouth:

Thanks in advance.
