A shot in the dark here, but perhaps the local machine does not know how to reach the remote machine where it is on a different subnet (assuming not a typo) 192.168.1.x
As a test once the VPN is connected, try adding the following route:
route add 192.168.1.0 mask 255.255.255.0 192.168.10.2
note: make sure 192.168.10.2 is the VPN/virtual adapter's IP. Change if not.
to delete the route:
route delete 192.168.1.0
if the above works, make sure the client has a static VPN IP, or a DHCP reservation, and make the route permanent:
route -p add 192.168.1.0 mask 255.255.255.0 192.168.10.2
You should also flush the cache
ipconfig /flushdns
You also should enable the "use default gateway option" on the VPN/virtual adapter, though it looks as if you have;
control panel | network connections | right click on the VPN/Virtual adapter and choose properties | Networking | TCP/IP -properties | Advanced | General | check "Use default gateway on remote network"
