Cisco VPN and Vista

On XP, if I wanted to VPN into work, a feature would allow Cisco VPN to be
launched at the logon screen, so a connection can be established prior to
logging on to the PC. I've tried using cached credentials, but since my
network uses Kerberos, my cached token is not renewed after i 1) logon with
cached credentials, then 2) establish a VPN. The feature is no longer in the
program, which leads me to believe that Vista no longer allows programs to be
launched at the logon screen. Is this true?
