This compatibility with NFS makes file sharing with Linux based OSes a lot easier and lowers the overhead of file transfers on devices that aren't as capable to handle the heavy samba utility.
To turn this feature on use the following steps:
Control Panel>Programs and Features>Turn Windows Features On or Off
Scroll down to Services for NFS and turn on Client for NFS to connect to NFS shares and/or Administrative Tools in order to manage NFS connections through Administrative tools in control panel.
While your here, take a look at what other features you can enable like TFTP client or Telnet Client.
Now, there are a couple of methods to connect to/mount an NFS drive in windows.
mount [options] //nfs-server-ip/share-name [drive letter]
Note: You will need to use the -u option if you connect to the share using a different username
GUI (map a network drive):
Go to "Start>Right Click "Computer">Map a Network Drive
Note: Click connect using different credentials if you use a different username/password to use your share
I will later add a post on how to add NFS to a D-Link DNS-323 NAS device
