http://cygwin.com/acronyms/#WJFFM. I'm using SFU/Vista/W7 NFS all the
time to build packages and keeping the share on my Linux box. The
availability of MSFT NFS in Vista and W7 (albeit only in the expensive
versions) was a reason to add MSFT NFS support explicitely to Cygwin.
If you want NFS shares preferred over SMB shares, you have to change
the provider order (Network and Sharing Center -> Change adapter
settings -> Advanced -> Advanced Settings... -> Provider Order).
NFS Network must be higher inb the list than Microsoft WIndows Network.
And make sure the uid/gid mapping is set up correctly (Windows 2008
AD mapping works fine, see the "UNIX Attributes" tab in the user/group
properties dialog in the "Active Directory Users and Computers" MMC
And make sure the security settings in the NFS client (starting with W7)
are correct. If the NFS server doesn't support krb5 authentication,
you should explicitly switch them off in the "Services for Network
File System" MMC Snap-in. Also, make sure that "reserved ports" is
enabled for best interoperability.

Still, an NFS client isn't just some arbitrary piece of software, it's a
filesystem driver, like ntfs.sys. There's no OSS code available which
provides this kind of FS driver for Windows.
