FIX: Error message when you try to connect to an SMB server from an NFS client computer: "Error 67: The network name cannot be found"

Symptoms

Consider the following scenario:
  • A client computer is running the Network File System (NFS) client and the Server Message Block (SMB) client.
  • A server is running the SMB server only.
  • The client computer and the server are not members of a domain, or they are members of different domains that do not have a trust relationship.
  • You log on to the client computer. However, your user name is not known on the server.
  • You try to connect to the server from the client computer by using the \\servername path instead of the \\servername\sharename path.
In this scenario, you receive an error message on the client computer that resembles the following:
Error 67: The network name cannot be found.

Cause

This problem occurs because of a problem in the NFS client redirector component of the Client for NFS service.
