Cisco PIX Firewall Problem

Hi,

I am currently having problems with my Cisco PIX Firewall, I am wanting to VPN to another network from my work network. When I use Cisco VPN client I can get a connection to the network I am wanting to reach. The problem is that once the VPN connection is successful I cant remote desktop to the computers on the network. Could someone tell me if there is a setting that I need to configure on the router/firewall to allow me access.

Thanks
Kent
