Sharing from Windows 7

Download WinNFSd-2.0.zip

Extract zip

Select the WinNFSd-2.0 > Right Click + Shift > Open command window here

Create a folder called C:\share

Back to command windows:

winnfsd.exe c:\share

That's it.

Test from GNU/Linux

$ mkdir ~/share
$ sudo mount sudo mount server.mydomain.com:/c/share /home/user/share

(Note: no trailing slashes).

Note: haneWIN is a popular paid for option. WinNFSd has not been developed since 2005 but works ok and gives a nice command window with logged output. WinNFSd is not installed as a service but this may be possible without too much trouble.
