1.0  Introduction
-----------------
This release of Microsoft(R) Windows NT(TM) 3.51 U.S. Service Pack 3 is
easy to apply from within Windows NT and changes only those files that
were originally set up on the Windows NT Workstation or Windows NT Server
system.  Service Pack releases are cumulative: they contain all previous
fixes, as well as any new fixes made to the system.


2.0  Installation Instructions for the Windows NT U.S. Service Pack
-------------------------------------------------------------------
Installing the Service Pack from a floppy disk:
1.  Insert Service Pack Disk 1 into the floppy drive.
2.  At the Windows NT Command Prompt, change to that floppy drive (that is,
    A: or B:) and type UPDATE.
3.  Follow the instructions given on the screen.

Installing the Service Pack from a CD-ROM:
1.  Insert the Service Pack CD-ROM disk into the CD-ROM drive.
2.  At the Windows NT Command Prompt, change to that CD-ROM drive, then
    change to the i386, MIPS, ALPHA, or PPC directory (depending upon whether
    you have an Intel(TM), MIPS(R), ALPHA AXP(TM) or PowerPC(R) CPU), and 
    type UPDATE.
3.  Follow the instructions given on the screen.

Installing the Service Pack from a network drive:
1.  At the Windows NT Command Prompt, type the command to connect to the
    network drive on which the Service Pack files reside.
2.  Change to that network drive and type UPDATE.
3.  Follow the instructions given on the screen.


2.1  User Notes
---------------
*** New ROUTE.EXE Command Line Argument

A new command line argument for ROUTE.EXE was added in Service Pack 2.  It
has been included in Service Pack 3 also. 
 
The new parameter is METRIC, and is described below:

ROUTE [-f] [command [destination] [MASK netmask] [gateway] [METRIC metric]]

METRIC
   The metric option is used to associate a cost/hop count for the 
   destination specified by the route entry. Generally this specifies the 
   distance in number of hops from the destination. If not specified, the 
   metric is set to 1 by default.

NOTE: The format of registry entries for persistent routes has changed due
to this new metric.  Persistent routes that were added prior to this new
format are not readable by the new code, so they will not be available
after applying the service pack.  See KnowledgeBase article Q138995 for
a detailed explanation and instructions.  A full-text searchable index
of the Microsoft KnowledgeBase is available at http://www.microsoft.com/kb/.

*** Emergency Repair Disk

If it is necessary to use the Windows NT Emergency Repair Disk to repair
your Windows NT system at some time after you apply the Service Pack, you
will need to re-apply the Service Pack after the repair is completed.  This
is because the Emergency Repair Disk repairs your system by restoring your
original Windows NT setup.  After the repair has completed, simply follow
the above Installation Instructions to reapply the Service Pack.


*** Adding New Components to the System

If new software or hardware components are changed or added to your system
after you have applied the Service Pack, it will be necessary to reapply
the Service Pack.  This is because the files taken from the original
Windows NT disk set may not be equivalent to the files on the Service Pack
disk set.  It is not possible to install new components directly from the
Service Pack media (such as a new keyboard or printer driver).  New
components must be installed from the original product media.


*** Installing Symbol Files from the CD-ROM

To install the symbol files corresponding to the new binaries in Service
Pack 2, do the following (assuming your CD-ROM drive is D:, your symbol
files are located in the C:\WINNT\SYMBOLS directory, and you are installing
the files for an x86 machine):

    XCOPY /S /U /D D:\SUPPORT\DEBUG\I386\SYMBOLS C:\WINNT\SYMBOLS

This will copy the Service Pack 3 .DBG files over the existing versions of
these files.  The XCOPY command shown will copy only those .DBG files that
are already installed (/U switch), and only those with a more recent time-
date stamp (/D switch).


*** Verifying the proper Firmware for Powerized ES and MX PowerPC systems

To install Service Pack 3 on your Powerized ES or MX PowerPC system, you
should first verify your Firmware is up-to-date.  Your Firmware should
have a date of September 15, 1995.  You may use the fw-title command in
the Firmware to verify this.  If you have an earlier ROM date, contact
your hardware manufacturer to get the latest release of the Firmware.


*** New APIs available with Service Pack 3

Service Pack 3 contains 3 additions to the Win32 API:

Fibers
------
A fiber is a lightweight thread that is manually scheduled.  Fibers do not 
provide advantages over a well-designed multithreaded application.  However, 
fibers can make it easier to port applications that were designed to schedule 
their own threads.  

Specific fiber APIs include:

ConvertThreadToFiber()
CreateFiber()
DeleteFiber()
GetCurrentFiber()
GetFiberData()
SwitchToFiber()

Winsock Enhancement
-------------------
Two new APIs, AcceptEx() and GetAcceptExSockaddrs(), have been added to the 
Windows Sockets family.  AcceptEx() provides a way to asynchronously accept a 
connection, obtain the local and remote addresses for the connection, and 
receive the first block of data, all within a single call.

Directory Monitoring
--------------------
One new API, ReadDirectoryChangesW(), has been added to enhance an application's 
ability to monitor directories.  It allows an application to receive notification 
whenever a change occurs in a directory.  These changes include file modifications, 
renames, and deletions.  Unlike FindFirstChangeNotification(), this API will return 
the full name of the affected file.

For complete details on these APIs, including headers, libraries and sample code, 
see the Win32 SDK Addendum for Service Pack 3, available in the "For Developers Only"
section of the Microsoft Web site at http://www.microsoft.com/devonly.
