question: do you have windows and linux running on the same machine as dual boot, or do you want to access a linux directory on computer A from a different computer B that runs windows? if the 2 computer model is what you are looking at, then you need to look into a program called samba. a simple google search for samba howto, or search of this forum would turn up some good sites and info.
hope this helps.
is a good thread from this forum about samba.
