I have had some trouble mapping an NFS Drive on Windows 2008R2.  It appears my issues relate to simple syntax.  I was using Amazon Workspaces and that runs on Windows 2008R2 Datacenter.  My NFS drive is running on on EC2 in Ubuntu on the same VPC.  I chose NFS over Samba hoping that it will make file transfers a bit quicker.

The command I used to map was \\localip\shared-folder E:

Where E: is the drive letter.  This is how it would look: mount \\\shared Z:

The other stumbling block I had was not seeing the drive in Windows Explorer.  By not seeing the drive in there I had a program that also couldn’t see the drive.  The answer to this situation was to run the mount command with a regular command prompt and not an elevated command prompt.
