Beating the Cisco VPN Client Error 51 On Leopard

I had this error popup today on my Mac OS X Lepopard 10.5.4 machine.

Cisco VPN Client Error 51

This is not cool as, well, I NEED MY VPN TO WORK!

Thankfully google came to my rescue. The solution is to execute the following in Terminal:

sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart

Thanks for the answer, VirtuallyShocking.com.
