If you have a problem connecting to an NFS share from your PC, or copying a file to or from the NFS share, there are several things to check:

• Do not use “root” as your NFS username. A number of NFS daemons see the root user as equivalent to no user, and will not allow it to connect.
• Do not bypass the Windows login, especially if your Windows username is the same as your UNIX username.
• Verify that your username has the correct rights for the directory on the host, usually both read and write.
• The host must be running pcnfsd version 2. To check that, go to a shell prompt and execute this command:
  

  rpcinfo -p | grep nfs

• In the NFS client setup, try both case-sensitive and case-insensitive operation.
• Also in the NFS client setup, try turning the “Cache Reads” and “Cache Writes” options on and off.
• On the host, check the /etc/exports file to make sure the directory you need is exported.

As you can see, there is no one optimal configuration for all NFS servers. Trial and error is usually the best way to determine what will work for a given setup.
