Afraid that doesn't give us much to go on. I assume where the DSL-G604T is not a VPN device, you are wanting to set up a Windows VPN using VPN pass-through on the D-Link. If so:

The basic server and client configurations can be found at the following sites with good detail:
If using as the server end, Server 2003 -configuration:

If using as the server end, Windows XP -configuration:

Windows XP client configuration:
http://www.onecomputerguy.com/networking/xp_vpn.htm
You will also have to configure the router to forward the VPN traffic to the VPN server. This is done by enabling on your router VPN or PPTP pass-through, and also forwarding port 1723 traffic to the server's IP. For details as to how to configure the port forwarding see:
http://www.portforward.com/english/routers/port_forwarding/Dlink/DSL-G604T/Point-to-Point_Tunneling_Protocol.htm
However, I could find nowhere in the DSL-G604T to “enable PPTP (or VPN)  pass-through” This unit may not support GRE and therefore not work. The setting is usually located in the firewall section. If you can’t get it to work  (you will get a 721 error when connecting) you will have to put it in bridge mode, making it a simple modem and add a compatible router.

The only other thing to remember is the subnet you use at the remote office needs to be different than the server end. For example if you are using 192.168.1.x at the office , the remote should be something like 192.168.2.x

Once this is configured you can then use services similar to how you would on the local network. You will not be able to browse the network unless you have a WINS server installed. Also depending on your network configuration you may have problems connecting to devices by name, though this can usually be configured.. Using the IP address is less problematic such as \\192.168.1.111\SharenName.
