New to the list, so forgive me if I miss some etiquette.

I have implemented Shrewsoft on several (10+) networks, and am pretty familiar 
with Juniper / Netscreen VPN's.  I ran into an issue where one of them stopped 
working.  After exhausting configuration options, recreating the VPN's, I still 
had the same issue.  From the firewall I can see the error message:

Rejected an IKE packet on ethernet3 from 63.229.228.145:1933 to 
63.253.251.138:500 with cookies 5258772399d01271 and 89bc291a23a99798 because 
there were no acceptable Phase 1 proposals.

The only thing that has changed is the firmware on the router.  I recently 
upgraded to  5.4.0r15.0 (Firewall+VPN) on the Netscreen 25.  I didn't beleive 
this would be the issue, so I upgraded a second Netscreen (5GT) with the same 
code version, and same thing.  Dial-up VPN is broke.  Rollback isn't an option 
as there was a security fix that I needed, but I also need the dial-up VPN.  
Since Netscreen doesn't support x64 clients I am running out of options.

My questions:
1.)  Can anyone else confirm that the Netscreen 5.4.0r15.0 broke there dial-up 
VPN?
2.)  Any idea how to reestablish connectivity?
3.)  I found the trouble ticket ID: Ticket #3752 (reopened defect) - I would 
like to note that I have the same issue on Windows 7, x64 even running Head 
development 2.2.0-alpha-9.
