Next, I think I understand what you want to do.
To share a non-Windows directory with Windows you need to do a TCP/IP to CIFS protocol translation. The Internet, long before the WorldWide Web used TCP/IP for communications so Microsoft had to invent their own. SMB, server message block, now called CIFS, common internet file system, is what MS came up with.
So, samba is just what you need. You configure it on the Linux system and handles the protocol adaption.
I suggest you use swat to confiure samba, swat is a web based gui tool.
What you are asking is something done every day in a mixed OS enviornment. have fun.
