VPN Connection Failing

I was having an issue with my new Macbook Pro not connecting with Cisco VPN. I had a few times this morning, but then stopped working. After a few google searches, I found this answer:

"This occasionally occurs for me as well, e.g. when I switch between two different Cisco VPNs. It seems to be a minor crash in racoon somewhere*. Manually restarting the process seems to do the trick for me:

$ ps -ef | grep racoon
0 5861 1 0 0:00.09 ?? 0:00.15 /usr/sbin/racoon
$ sudo kill 5861
$ ps ax | grep racoon
)>
$ sudo /usr/sbin/racoon
$ ps -ef | grep racoon
0 6786 1 0 0:00.08 ?? 0:00.15 /usr/sbin/racoon -x
(Don't know what the '-x' param does, it's not mentioned in the man page)
