Cisco VPN connection failing

I'm been using a Cisco Systems VPN client Version 4.0.3(C) from home for over a year to connect through our PIX firewall at work.  Recently it I randonly get the error message:

"Secure VPN Connection terminated locally by the Client. Reason 412: The remote peer is no longer responding. Not connected."

I have a cable connection at home and have tried connecting directly to the cable modem (bypassing the D-link wireless router). I am running Windows XP on my IBM Thinkpad with all the latest updates.

One day I can connect, the next I cannot. Any suggestions?

Did you recently install SP2 on XP?
If yes, you may need to upgrade from 4.0.3 to 4.0.5 or 4.6
Both of these releases were published specifically for SP2 compatibility.
Also, do you know if you have hotfix 05-019 ? It's causing all sorts of networking issues lately..

I have both SP2 and the hotfix.  It must have happened after the hot fix because it only startered a few weeks ago.  Will a new version of the VPN Client help or should I uninstall the hotfix?  Do you know where I can get the new version of the VPN Client?
You can get the latest VPn client direct from Cisco if you have a CCO login, else you can call them with your PIX serial number and they should give you access to download the client.

I would start by uninstalling the hotfix. This one has caused a whole lot of heartache because it "fixed" some things that were broken in XP, fixed in SP1, broken in another hotfix, re-fixed in SP2, then someone had the big idea that it wasn't fixed in SP2 after all, they needed to fix it again...

If that doesn't work, I wouldn't hesitate to upgrade to the new version client.
