LinuxQuestions.org - Is this possible with any distribution?

Hi, I'm considerably new to linux(I have been using it off and on for almost two years with distros ranging from Slackware to Mepis, but I still wouldn't consider myself experienced) and I was wondering about setting up my two networked computers for File Sharing.

What I want to do, is Dual Boot with my main comp(WinXP and Linux) and use linux on a second comp, and completely share the network. What I mean by that, is I want to be able to access both Win/Linux hard drives on my main comp using my second comp, and be able to access my Linux drives with WinXP on my main comp, etc.

I'm not entirely sure this is possible. I know I can access my windows hard drive on my main comp by mounting it in linux, but I don't know how to access this comp at all over the network from my second comp. I also know that, right now, Windows can't access my linux hd on the same comp. Would I have to create seperate partitions on both linux drives for /home/ and use a different file system type that Windows can read?

(as a note, I'm looking towards Slackware or Debian for both comps, but that definitely isn't set in stone)

So, is this possible at all?

Thanks in advance for any help at all.
