Network conections

I am looking to do some work at home. How can I connect to my server from my desktop at home. Home I have a DSL. Work is a partial T1. The server is a MS2003 and Home has XP Pro. What is the most efficent, easy and secure way of doing this and how? I know .... good luck (easy, efficient and secure don't ever seem to go hand in hand) But I really could use some help here. The office server doesn't have a firewall .... provided by the IP provider or router .... also by the IP provider. I use a Eithernet connection into a 10/1000 Foundary Switch and then into the server.

wait wait, you want to connect from home to your server?

if it's a 2003 server, you already have VPN capabilities built into it from the routing and remote access mmc, but it's sorta different, as you'll need to use a public IP to VPN into the server, then you have use remote desktop connection to enter the station's private ip (internal) to see your desktop and login

i know you say there is not firewall at work, but you need to obtain a public domain name or ip address to do this, on your router, you also have to setup a VPN passthrough rule so you can hit the server using PPTP protocol (L2TP is sorta advanced for this purpose)

but it's possible, or like he said, get a router with VPN capabilities, or maybe your current router already has those features?
