Use this chapter to set up and manage SMB service in
Mac OS X Server.
Mac OS X Server can provide the following native services to Windows clients:
 Domain login. Enables each user to log in using the same user name, password,
roaming prole, and network home folder on any Windows computer capable of
logging in to a Windows NT domain.
 File service. Enables Windows clients to access les stored in share points on the
server using Server Message Block (SMB) protocol over TCP/IP.
 Print service. Enables Windows clients to print to PostScript printers with print
queues on the server.
 Windows Internet Naming Service (WINS). Enables clients to resolve NetBIOS
names and IP addresses across multiple subnets.
 Windows domain browsing. Enables clients to browse for available servers across
subnets.
File Locking with SMB Share Points
File locking prevents multiple clients from changing the same information at the same
time. When a client opens a le (or part of a le), the le becomes locked so the client
has exclusive access.
Before a read or write is performed on a le, the lock database is checked to verify the
lock status of the le.
Strict locking, enabled by default, helps prevent multiple clients from attempting to
write to the same le. When strict locking is enabled, the SMB server checks for and
enforces le locks.
Opportunistic locking (oplocks) grants exclusive access to the le similarly to strict
locking, but also permits the client to cache its changes locally (on the client
computer). This type of locking oers improved performance.
