Issue 1

Assume Assume that you try to use a Universal Naming Convention (UNC) path to access a network file system (NFS) share from a computer that is running one of the following operating systems:
  • 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

Issue 2

Assume that you use a UNC path to access an NFS share from a computer that is running one of the following operating systems:
  • 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.
