Hi All,

***Cisco VPN Client - Connection Error Reason 412***

I am trying to connect office through my laptop from home. But I am
getting following error. The log is also inclued here.

After searching a lot on internet and trying solutions I am posting
question here.

1) I can connect from home if I use different laptop with XP
installed.
2) Not able to connect from laptop which has Vista Home Premium.
3) I tried IPSec over TCP.
4) I tried UseLegacyIKEPort=1 and ForceKeepAlive=1.
5) I tried other versions of VPN Client such as 4.8
6) I can ping VPN server
