Netscreen-Remote VPN connection does not pass traffic

I have a problem with a Netscreen-remote VPN client attaching to a Juniper
Netscreen SSG5 firewall. XP systems seem to have no issue connecting to the
VPN and passing traffic to all the internal networks and the Internet
(everything is funneled through the VPN.) My Vista system can connect, but
cannot pass traffic.

Juniper does not have an answer (told me it was a Vista issue.) There is no
firewall turned on in on my system and I do not have any enterprise network
protection (like the Norton suite), just AV. There are no external firewall
rules that are preventing me from passing traffic.

I am installing using the Netscreen-remote VPN Client 9.0r2.exe installation
file (this shows as version SafeNet SoftRemote 10.8.1 (Build 10)

I have found similar issues on the net, but all of them claim this version I
am using would fix it.

Anyone have any thoughts on this?
