If so, it also may be a good chance that you use the Cisco VPN client and have run into this annoying message:

Error 51: Unable to communicate with the VPN subsystem

Thankfully, the solution is rather simple. Open up your favorite terminal client and simply type:

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

Enter your password and it’ll restart the subsystem. Then just re-open the Cisco VPN client and you’re golden.
