Can't connect to Remote VPN on ASA using Windows L2TP over IPsec

Hi all,

This is my first VPN configuration I have done with an ASA device.  I am trying to setup a remote access VPN using windows L2TP/IPsec.  I used the IPsec (IKEv1) Remote Access VPN Wizard in the ASDM to set it up.  I have a user in the AAA/Local Users section configured and am using a Preshared Key. 

When I try to connect in Windows 7 I get the error:

Error 789:  The L2TP connection attempt failed because the security layer encountered a processing error during the initial negotiations with the remote computer.

Below is my config on the ASA.

In windows the VPN is configured to connect my ASA WAN IP of 198.145.XXX.82

I am using the same user and pw to connect as set in the ASA AAA/Local Users.

The security tab is set to L2TP/IPsec and the presharedkey is checked and entered.

CHAP and MS-CHAP2 are the only protocols checked.

Any help would be great.
