My Powerbook hard drive recently crashed, so when I got my new one, I had to re-install all the software, including the VPN so I can access my company's network wirelessly. This used to work before the crash, but now when I log into the VPN and try to access a network folder, I get this error message. If I disconnect from the VPN and plug the computer into the wall, it works perfectly. Anyone have any idea what is going on? And why would this not work now, but work before my hard drive crashed?
