We have a Cisco ASA 5505 configured to host VPN traffic. It's worked seamlessly for about 3 years. It's domain-integrated, meaning users login using their domain user/password combos.
While I periodically see a VPN client machine fail to connect to the network, I've never seen a VPN client machine connect to the network but then be unable to "see" the network. While VPN indicates that connected to the network on the client machine, I'm unable to hit any computer in the network using an IP address or a computer name. I'm unable to ping the network gateway as well.
Moving the VPN client machine to different location does no good. The connection succeeds, but the network is not visible.
The Cisco 5505 is configured with split tunneling.
The client machine is running Windows 8. (If I was to bet on the cause of the issue, I'd bet on this.)
While the VPN client indicates that a connection is established. I'm not sure that's the case.
