VPN (Netgear) established, but cannot access computer on network

I’ve finally manished to establish connection to network via VPN, the problem is that i can’t browse or access my remote network, thou the computers sometimes show upp in the network window.
I’m able to ping the computers in the network.
I can also browse the webpages located on one of the computers IIS, but only with it’s IP-adress not by name.
What seems to be the problem?
