How to remove the Cisco VPN client

I am trying to remove the Cisco VPN client R4.01 from my machine to reinstall it.  The client has ceased to function since I joined my computer to a SBS2003 domain.  I believe what happened is that the change in my machine name affected the client.  I tried the add/remove program router and got the error message "remove plugin failed error 1722".  I tried to remove it from the registry and the Program Files and it respawned it self when my machine rebooted.  

I've looked for the obvious things to remove it, but no luck.  Trying the repair option in add/remove programs doesn't fix the issue.  

I'm looking for suggestions on how to clean it out so that I can get a fresh install back on my machine.

Thank you for the input.  I wasn't blocked on the domain from removing it as I control the domain.  Going through the registry got it removed.  I had tried that before, but must has missed some keys.
