comment NFSv3 client differences in read/write performance
I would check network latensy first. Second what you can do is to check with packet trace time difference between TCP ACK reply ( time when server received TCP request) and RPC reply. This difference will indicate how long server was processing the request. After that you know where the problem is: server or network.

comment Create and Manage Windows NFS Shares for Linux Clients with AD Authentication
you should enable RPCSEC_GSS on NFS server. AD is a kerberos server with build in LDAP. Check here blogs.technet.com/b/filecab/archive/2010/05/13/…

comment NFS: client does not see new files created on server (caching?)
if you have exported /media/data/ on the server how you can expect that changes in /data/ will be visible on the client? /data/ is not a subdirectory of /media

comment Passing Linux NFS traffic through Windows Server 2008
your nfs traffic reaches the nfs server. Check the export file. You server sees client packes coming from e different IP address and rejects the mount request.
