ISA 2004 SP2 killing Juniper dsTermServ Session?

How do I permanently allow Juniper TS (dsTermServ Module) via Juniper RSA
SSL VPN to maintain a connection through ISA 2004 SP2?

I can connect from my home workstation to my office workstation using the
Juniper RSA SSL VPN with RSA SecurID and initiate a dsTermServ session.
After a minute or two of inactivity, the TermServ session times out. I get
the blinking one inch square disconnect icon in the upper right corner.

The VPN session (HTML page) stays connected, my dsTermServ terminal services
session times out. The Juniper system I'm logging into was recently upgraded
to version 5.3. My connection to the earlier version (4.x) never timed out.
Now, I minimize the TS (remote desktop) window, come back in several minutes
and find that the TS session has timed out.

A dsTermServ connection via a laptop bypassing ISA2004 (connected directly
to the router) does not timeout.

Here's the network:

home workstation---ISA2004SP2 (SBS2003SP1)---router---Internet
device---Internet---corporate LAN with Juniper SSL VPN---remote workstation

The kind folk at Juniper have not been any help. I have not made any changes
to ISA or AD between the two versions of Juniper dsTermServ.

My ISA 2004 SP2 is loaded on my SBS 2003 SP1 premium box. I'd break all the
wizards if I upgraded to ISA 2006. Might there be a Hotfix for 2004?

The dsTermServ Module is already an approved exception on my client desktop.
If I disable the Windows Firewall service on the desktop, the TS session
still disconnects.

I created/set the following registry keys on my single server. But this did
not help either.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

* KeepAliveTime was kept at 30000 (decimal)
* KeepAliveInterval was kept at 5000 (decimal)
