  2. If necessary, connect to the computer you want to manage.

  3. Right-click Server for NFS, and then click Properties.

  4. Click the Filename Handling tab.

  5. Do one of the following:

    • To enable case-sensitive file and directory name lookups, select the Enable case sensitive filename support in Server for NFS check box.

    • To disable case-sensitive file and directory name lookups, clear the Enable case sensitive filename support in Server for NFS check box.

These changes will not take effect until Server for NFS is restarted.
You also need to disable Windows kernel case-insensitivity in order for Server for NFS to support case-sensitive file names. You can disable Windows kernel case-insensitivity by clearing the following registry key to 0:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel
DWORD “obcaseinsensitive”
