Why would you want that? NFS isn't designed to be used on windows machines and causes problems in the long term. There's also no security in native NFS, so an extention was made called PCNFS, which would add some kind of authentication at mount time; I have seen a client which could use native NFS though. You can download a 15 day evaluation demo at www.xlink.com
Please note that you abondon file-security when NFS-exporting filesystems to windows clients ( also true for unmanaged linux clients ).
