When I try to connect to the cisco vpn client, I get this error:

secure vpn: connection terminated locally by the client
reason:422 failed to enable virtual adapter

I googled this error, and several sites suggested uninstalling/reinstalling cisco vpn client. That didn’t help.
Btw, I see the Cisco VPN Adapter under my network connections.

Couple other sites suggest disabling internet connection sharing on vista. This is a windows xp machine with sp3. In my LAN properties, the “internet connection sharing” checkbox is unchecked.

There are couple firewalls, which I disabled. Still no luck.

I had a pc problem couple weeks ago, and I had to reinstall everything from scratch. I didn't receive this error before.
How can I resolve this issue?

Thanks in advance.
