Yesterday there was IPS alert: Invalid Netbios Name id=3357, while a Cisco VPN client was connected to the network. The employee ran a virus check-nothing found. Today the employee can not connect to the ASA firewall to set up a VPN connection--the VPN client's authentication box does not show up. The Ciso VPN client's 'connection' entry was deleted and reconfigured, still can not access the ASA. Meanwhile, other clients are able to VPN in. The client was able to access the network yesterday from a hotel. Could the cause of inability to VPN in be due to the after effect(s) of Invalid Netbios Name? Any assistance in trouble shooting would be appreciated.
