NFS Share works as root but not as a user

Hi Guys

I can write to my NFS share as the root user but when i try to do a touch i get a 'touch cannot create' error. Also, if i try to copy a file into the NFS share I get an I/O error.

I've set the everyone group to have full control, and as I say it works fine when using root user but not any other unix user.
