Client being behind a nat router
Client running XP/SP2
Can you be more specific? Is this error seen on the client log, or on the server end? What is the server end? PIX, ASA or VPN3000?
What other symptoms are you seeing?

1) That client is way too old, especially if you're on Windows XP SP2.  You should be using v4.8 (v4.6 at the very least).
2) Why are you using TCP to try & establish your VPN connection? Using the default tunneling over UDP works fine, & is much better IMHO.
3) What's the VPN server box?  Cisco VPN concentrator or what?  If it's not a Cisco box, don't bother using Cisco's VPN client to connect!

 Are you by chance using a Dell WiFi card?  There are known issues with some of these:

Are you still working on this? Can you close out this question before the cleanup crew gets around to it?
