I had the ciscovpn client vers 4.8.01.300 installed on a Windows XP SP1 computer. Uninstalling VPN Cliemt left my IP stack hosed. After uninstalling the vpn client, I could not:
1. ping the computer from other LAN computers
2. access shared resources on the computer from LAN computers
3. access LAN resources using Netbios names - including map drives, etc..
4. use browser to access websites - trusted and secure as well as "ordinary" ... they'd all time-out
I tried reinstalling the IP stack and winsockets using MS's instructions for Windows XP SP1 - it didn't work and changed nothing.
Further note: IF I reinstall the vpn client, activate a connection to the vpn concetrator it had been using, then diconnect and turn off the Cisco VPN Service, the computer behaves normally; uninstalling the VPN client at this point produced the same results - the computer wouldn't really conect to LAN resources or allow connections from elsewhere on the LAN.
The machine behaves as if the firewall installed by the VPN Client was left behind and turned on.
Any clues on how to fix so I can uninstall the vpnclient and have normal operation on the LAN and Internet connectivity.
