Maybe you can have a solution, but not really the better one : Use of NTFS diretory redirection : you can have a directory in a ntfs drive that is pointing to another directory or drive of the server. The two must be in NTFS. In fact, it's nothing else than the Unix link system on w2k.

Also, if i'm remember, DFS is doing the same thing, and more easier, but the DFS client have to be installed
