Are you saying that after the PPTP connection is made from client to server that your client can access the server via IP but is not able to access any network services on other machines ? Did you double check that IP forwarding is enabled and what about NAT rules ? Are you natting all traffic so it appears to come from the server or is your network setup to route traffic to the client network ?
