The command prompt crashes in Windows Server 2008 R2 or in Windows Storage Server 2008 R2 when Nfsfile.exe tries to set the GID of a folder

SYMPTOMS
Assume that you are trying to set the primary group of a folder to a specific group identifier (GID) on a computer that is running Windows Server 2008 R2 or Windows Storage Server 2008 R2. To do this, you run the following command at a command prompt:
nfsfile.exe /r g=<gid> <folder>
In this situation, the command prompt crashes.

Note Nfsfile.exe is a command-line tool that lets you manage files that are created on a share with the Allow unmapped user UNIX access Network File System (NFS) setting enabled. This command-line tool is included in Windows Server 2008 R2 and Windows Storage Server 2008 R2. For more information about how to use Nfsfile.exe, download the following Word document from the Microsoft website:
CAUSE
The issue occurs because Nfsfile.exe tries to release memory that is allocated to a user account instead of to a group account.
