Mounting an NFS filesystem from Windows on Linux.
The user:group of the files was being set to nobody:nobody
To override this, you can use:
rw,vers=3
in your options in /etc/fstab

Using mount
we could see that the mount options were defaulting to nfsv4 (which doesn't support changing the user? - it certainly doesn't offer setting the user in the available mount options.)
