Server for NFS
With Server for NFS, a com puter running the Microsoft Windows Server 2003 R2 operating system
can act as a Network File System (N FS) server. Users can then share files in a mixed environment of
computers, operating systems, and networks. Users on computers running NFS client software can gain
access to directories (called shares) on the NFS server by connecting (mo unting ) those directories to their
computers. From the viewpoint of the user on a client computer, the mounted files are indistinguishable
from local files.
UNIX computers follow advisory locking for all lock requests. This means that the operating system does
not enforce lock semantics on a file, a nd app lications that check for the existence of locks can use these
locks effectively. However, Ser ver for NFS implements mandatory locks even for those locking requests
that are received through NFS. This ensures that locks acquired through NFS are visible through the
server message block (SMB) protocol and to applications accessing the files locally. Mandatory locks
are enforced by the operating system.
Server
for NFS Authentication DLL vs. Service for User for Active Directory domain controllers
On a Windows Storage Ser ver 2003 R2 storage server, Server for NFS depends on a domain controller
feature called Ser vice for User (S4U) to authenticate UN IX users as their corresponding Windows users.
Windows Server operating systems prior to Windows Server 2003 and Windows Storage Server 2 003
do not suppor t S4 U. Also, in mixed domain environments, legacy Services for UNIX (SFU) , Services for
NFS and Windows Storage Server 2003 NFS deployments do not use the S4U feature and still dep end
on the Ser ver for NFS Authentication DLL being installed on domain controllers.
Therefore, the administrator nee d s to install the Server for NFS Authentication DLL on Windows 2000
doma
in controllers when:
• The NF S file serving environment uses previous NFS releases (NAS, SFU, and so on).
• The Windows domain environment uses pre-2003 domain controllers.

and R2 MSNFS.
