  • Windows Vista

  • Windows Server 2008

  • Windows 7

  • Windows Server 2008 R2

The NFS share is hosted on a UNIX-based NFS server. In this situation, you cannot access the NFS share. Additionally, you receive the following error message:

Network error

  • Windows Vista

  • Windows Server 2008

  • Windows 7

  • Windows Server 2008 R2.

The NFS share is hosted on a UNIX-based NFS server. However, when you try to save some files to the NFS share by using an application such as Notepad or Wordpad, you receive the following error message:

Filename not valid

Cause

This issue occurs because Windows does not locate the NFS share correctly.
