How to mount an nfs share

I have also created NFS share: (dun) on my WD Share Space (it’s IP: 192.168.102.150)

then I allowed all IPs:

i.e. I have indicated “*”

and then I am trying to mount (in win xp Win NFS client):

mount 192.168.102.150:/nfs/dun W:

but getting message Network Error -67  (The Network name coud not be found).

Is my sintaxis correct?
