if you visit the resnet site resnet.tamu.edu and click on one of the help links on the left it should take you to the computer services help website. Look around there for VPN. Windows already has VPN built in, it just needs to be set up. There are other third party VPN clients available though.
All you need to do is find the VPN download, I'm pretty sure its still there haven't checked it in a while. And run it and it should set everything up for you.
