mount drive over internet

I have a drive mounting related question.

How would I go about mounting a shared drive at my house from my work? Here is some information so you can help:
1. My PC at work is running XP on a Domain
2. My PC at homs is running server 2003
3. At work, ports 8000+ are open
4. I have a router with port forwarding
5. (if it helps, I have fedora boxes at each location as well. I can ssh/scp just fine, but I'd like a mounted drive at work from my home lan)

Straight forward so far, eh?

I am not familiar with the protocol, which ports to use, and what to start clicking on on each computer to make it happen. Like, do I set up the drive a "web share" or "share". What about the domain privaleges? Etc......


Someone out there has to have done this at one point. I have seen it done before too.

Thx for any help
