Connecting to Windows server 2012 R2 NFS share

[ArwenD]

We currently have an HP-UX V. 11.11 that was connected to a windows server 2008 R2 NFS share utlizing Services for Unix on a Windows server 2003 to map the unix users to our Windows domain users. We have since moved our NFS server to server 2012 R2. We map the share using /etc/fstab with the following line:

servername:/share /tmp/share nfs rw 0 0

The default configuration of windows server 2012 R2 does not allow us to map the share. We have to disable support for NFS V 2.0 and 3.0 for the share to mount. From my reading here: in order to map the unix servers with domain users the minimum supported version for this is 3.0. 

When I run rpcinfo -p localhost | grep nfs, I get the following results:

100003     2    TCP      2049   nfs

100003     3    TCP      2049   nfs

100003     2    UDP     2049   nfs

100003     3    UDP      2049   nfs

So it seems like V 3.0 is supported, but will not connect to the windows share. Any ideas???
