There are multiple issues involved here and you solve them depends on what you're really trying to accomplish.
First, are you trying to share the data with existing Unix/Linux systems that have it NFS-mounted? If so, you really, really need to talk to the storage guys because you're crossing security domains - CIFS and NFS are very, very different. You will have a challenge mapping Windows userids to NFS UID/GID pairs.
If you're not sharing with any Unix/Linux systems, get the filer to present CIFS at all possible. NFS and CIFS are licensed separately on a filer but if you the license, it's a LOT simpler.
If you can't present CIFS and it's just for your guest, you have to ask yourself how badly you want to talk NFS. Windows doesn't include an NFS client so you'll need to purchase one. And you will still need to figure out the uid/gid mappings.
Your last option that I'm aware of is to create a datastore on an NFS export and present a vmdk from that to your guest. You then have normal NTFS security on it and it won't confuse your Windows community.
