Shrew for Vista 64 and juniper Netscreen SSg5 IPSec configuration help

Hi,
We have a Juniper SSG5 version  6.0.0r4.0 .  We have an existing VPN that we use with the Netscreen Remote 9.04 Client successfully.  We have an employee with Vista Home Premium 64 at home now and are looking into Shrew VPN Client to support 64 bit clients. I have setup a policy on her system using the Shrew and it seems to be successfully negotiating Phase 1 but I am having trouble getting the Phase 2 to successfully connect (I think) with SSG5

I am getting this logged on the SSG5 when I try to connect from the Shrew client on her machine.

IKE xx.xx.33.215: Received initial contact notification and removed Phase 1 SAs.
IKE xx.xx.33.215: Received initial contact notification and removed Phase 2 SAs.
IKE xx.xx.33.215: Received a notification message for DOI 1 24578 INITIAL-CONTACT.
IKE xx.xx.33.215: Phase 1: Completed Aggressive mode negotiations with a 28800-second lifetime.
IKE xx.xx.33.215: Phase 1: Completed for user TEST.
IKE xx.xx.33.215: Phase 1: IKE responder has detected NAT in front of the remote device.
IKE xx.xx.33.215: Phase 1: IKE responder has detected NAT in front of the local device.
IKE xx.xx.33.215: Phase 1: Responder starts AGGRESSIVE mode negotiations

My configuration on the SSG5 is as follows: (just VPN parts)
set user "test" uid 1
set user "test" ike-id u-fqdn "test.mydomain.com" share-limit 1
set user "test" type  ike

set policy id 3
set log session-init
exit
set ssh version v2
set config lock timeout 5

My Shrew configuration is:

Can anyone help me with correctly setting up the Shrew Client without having to change my existing Netscreen configuration and policies (if possible) If not then I can update all the users as well.

Thanks!
