no luck yet - posted a slightly different post with more info - we're using Clearswift's minesweeper for web product (coz we have to, so using MS proxy isn't an option). We got no help from our local Clearswift agent.
We also cannot turn off the proxy on the ISA FW
We're trying to tap the brain of an MS server expert when he's here later today (if he has time). If anything it'll give us guidance on whether our technical approach is valid or not. (the VPN itself works - so is a "server or network" issue). I'll put reply after we see him
apologies for the delay in an update. the ms guys where a few days late.
after checking various logs, our problem is due to the ISA server running a web proxy. Easist fix would be to turn the webproxy off - in our case we need the web proxy for the "LAN" based clients so not an option. A post has been made inside MS re how to turn off the web proxy for just the VPN client network.
if that doesn't work, we need to redesign the way our remote stuff comes in.

I am not sure if you have already solved this problem, but check your XP clients for entries with event ID 40961 in the events log. If you find instances of this event ID, the following articles might help.
