Open Services for Network File System: click Start, point to Administrative Tools, and then click Services for Network File System (NFS) .

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

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

Click the Filename Handling tab.

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.
  
  

Click Apply.

	Important
	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”

Open a command prompt.

To enable case sensitivity, type:

nfsadmin server [ComputerName] config casesensitivelookups=yes

To disable case sensitivity and optionally specify the case of file names returned by Server for NFS, type:

nfsadmin server [ComputerName] config casesensitivelookups=no [ntfscase={upper | lower | preserve}]

	Important
	These changes will not take effect until Server for NFS is restarted.

	Notes
	The ntfscase option sets the case sensitivity for the NTFS file system. The default case sensitivity is preserve (preserve case). To view the complete syntax for this command, at a command prompt, type: nfsadmin server /?
