Are you using NIS for your NFS export ?

Try exporting to an IP address – maybe that NIS error is a red herring

yes NIS is my NFS Authentication protocol

Not 100% sure what you mean by export to an IP.  I have attempted to mount the NAS server IP address and I get the same errors.

I found out yesterday that if I don't list my NIS server, or if I list it incorrectly the Share actually works for redhat,  the CIFS share breaks however because it cant authteticate to the NIS server.

So for some odd reason the issue seems to be with contacting the NIS master.

Well – NFSv2/3 doesnt really authenticate

All the VNX server does is to make sure that the client’s IP has the permission for mount/access/read/write

In case you are using hostnames in the export clause then we would use DNS or NIS to do a reverse lookup of the IP to a name

So if you export to the IP we should be ok with a non-working NIS

Other use if NIS would be if you are using multi-protocol to resolve UID to Unix username

First thing I want to mention... You talk about an export clause.  Which to me is an actual statement,  this is actually for an VNXe.... which is all done via Unisphere gui.... 

Mutli-Protocol to resolving UID  to Unix name is exactly what we are attempting to do .  

as I mentioned,  when I take out the NIS domain, or type it incorrectly  then the NFS mounts work. ... However it breaks the Multiprotocol on the windows side

and apparently when I put it in correctly  then the EMC cannot find the NIS domain.     When I enter the "Domain"  for the NIS domain  do you know how its supposed to be formatted?     for me my NIS domain is Solar,  and I have the IP address of my NIS server in there.   

does that sound correct?
