Our company has been using the Cisco VPN client on about 20-30 varied W2K laptops for over a year with no problems. In the last few weeks on 2 new installs of the client, this would happen: The install would go flawlessly, system would reboot, and upon coming back up (without even running the client) the network would not send or receive. W2K would detect that there was a network connection, but no data would pass. Cisco support has no idea why (and hasnt heard of it). I was using client version 3.1.1 and after the problem occurred, I tried version 3.6.4 with the same results. If I uninstall the client and reboot, the network is fine. On a different machine that was running the old vers fine, I uninstalled and tried installing both the old and new version. Both installs had the problem, so now a laptop that did work, does not. Installing on a Compaq Desktop also running W2K works fine. Any ideas????
