I want to take a physical disk (or part of a disk) in one machine (call it machine-A) and I want to make it available in another machine (machine-B). But I don't want to map a network drive. I want it to appear in machine-B as a physical drive. Even though it is not a physical drive.

The reason I want to do this is i want the ability to create shares in machine-B on that drive. Since I cannot do that on mapped drives, I need to use some utility that fools machine-B to think that it is a physical drive, and treat it as such.

Both of these machines are windows server 2003.

I heard about NFS, It sounds like what could be the solution to my problem. But isn't that a Linux/Unix protocol? What tools can I use to make this happen? Are there any open source solutions?

I don't care what the solution is, as long as it achieves the end result, preferably open source solution though.

Thanks for reading guys and gals!
