I have several users with the Cisco VPN client (5.0.01.060) that connect to my ASA5540 (code 8.02). They get connected to the ASA fine but can not access any network resources that are at the VPN site. If they uninstall the Cisco client and re-install our old Nortel client (on the same machine) they can access all of the network resources fine. It is not the Cisco VPN client as the same software works on multiple other client workstations and the same ASA5540.
I have this problem too.
