NFS File Sharing on Server 2008

[nwinn84]

I am trying to use NFS file sharing to share a file to mount as a directory on an AS400. When I go to the C: drive on server 2008 and set up the NFS File share and click Apply I get the following message: "A subdirectory of the path has already been shared or you are trying to modify the properties of a share that is online."
I have no shares at all on this server and cannot get past this error message. Any suggestions?

Are you trying to create a share at the root of C: or are you sharing a particular directory?
