Cisco VPN disconnects after 5 seconds with error 422

I had problem with my VPN when try to access the office network. VPN used to disconnect connected after few seconds. I have gone through the few forums and finally got the solution.Then i have made the below changes and its worked for me.

My computer name has always been localhost (no, really, In the system->computer name dialog, I named it localhost). This screws up the network for other windows machines, because if they try to enter \localhost\ in the address bar, windows reports a network name collision.

And apparently Cisco VPN doesn't like my computer name either.

But i am not sure whether this fix is correct or not. but it worked for me :)

Thanks
