1.0  Introduction
This release of Microsoft Windows NT 4.0 Service Pack 3 Beta 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, and any new fixes made to the system.

1.1  What's New in Service Pack 3
RPC Transport

This service pack includes new versions of the remote procedure call (RPC) run-time dynamic-link library (DLL), the RPC subsystem service (Rpcss.exe), the Microsoft Interface Definition Language (MIDL) compiler (Midl.exe), and several new RPC header files. These changes provide enhanced support for RPC message queuing, which is a feature of the upcoming Microsoft Message Queue Server (MSMQ). In order to use message-queuing in an RPC client/server application on Windows NT 4.0 you must have Service Pack 3 Beta installed on both the client machine and the server machine. 

If you are developing RPC applications that support MSMQ, you need the new RPC run-time DLL, the new RPC subsystem service, the new header files, and the new MIDL compiler. Also, RPC applications must support message queuing in order to use the following new features:

The MIDL [message] attribute.

The ncadg_mq protocol sequence.

The RPC_C_MQ_* endpoint flags in the RPC_POLICY data structure.

The RpcBindingInqOption and RpcBindingSetOption functions.

For more information on using message queuing in your RPC applications, see RPC Message Queuing in the Windows NT 4.0 Help or refer to the documentation in the upcoming MSMQ software development kit (SDK).

CAPI 2.0

The Microsoft Cryptography application programming interface (CAPI) provides developers with core cryptographic and certificate functions. CAPI 1.0 supports public-key and symmetric-key operations, such as key generation, key management, key exchange, encryption, decryption, hashing, digital signatures, and verification of signatures. CAPI 2.0 (the upgrade contained in this service pack) includes this core cryptographic functionality as well as certificate-based functionality, which is required for developers who want to use certificates with these public-key operations and perform the necessary encapsulations and encoding to apply certificates within their applications. 

CAPI 2.0 uses a service-provider model in which cryptography is provided by Cryptographic Service Providers (CSPs). This model allows developers to easily adapt their applications to evolving cryptographic technologies and government export policies. One CSP is provided with this service pack (the Microsoft RSA Base Provider), which gives users and developers access to exportable cryptography. 

CAPI 2.0 supports existing standards, such as X.509 v.3 certificate formats, ASN.1 encoding, and both PKCS #7 and  #10 for encapsulation. This allows applications using CAPI to interoperate with other certificate-based systems that adhere to these standards.

The release version of CAPI 2.0 includes several updates to the developers release version of 9/96, including both parameter changes and naming changes.  These changes are reflected in the Crypt32.dll and Wincrypt.h files. Please consult the CAPI 2.0 documentation for details.

Microsoft NetMeeting 2.0 Beta 3 

Microsoft NetMeeting 2.0 enables real-time communications and collaboration over the Internet or a corporate intranet, providing standards-based audio, video, and multipoint data conferencing support. From a Windows 95 or Windows NT 4.0 desktop, users can communicate over a network with real-time voice and video technology. They can share data and information through true application sharing, electronic whiteboard, text-based chat, and file transfer features. 

NetMeeting 2.0 Beta 3 is the first version of NetMeeting for Windows NT to fully support application sharing. This functionality requires Windows NT 4.0 Service Pack 3 Beta. It is important that you install the Service Pack before installing NetMeeting 2.0 Beta 3. If you use NetMeeting 2.0 Beta 3 on a computer that does not have Service Pack 3 beta installed, you will be able to view and control applications shared by other NetMeeting users, but you will not be able to share applications from your computer. NetMeeting 2.0 Beta 3 is identical to NetMeeting 2.0 Beta 2 in all areas other than application sharing. For more information on NetMeeting 2.0, please refer to Netmeet.txt, which is located in the NetMeeting directory on the enclosed compact disc.

This product will not be included with the final release version of Service Pack 3 for Windows NT 4.0. It is included here to facilitate beta testing. When Net Meeting 2.0 is released, it will be available at 

DirectX 3.0

Service Pack 3 Beta provides support for DirectX 3.0 with the exception of Direct 3D hardware acceleration. Direct 3D software emulation is supported. 

ODBC 3.0

This service pack includes the latest version of Microsoft's Open Database Connectivity (ODBC) API. ODBC 3.0 provides an updated ODBC Control Panel and ODBC Administrator interface that uses tabbed controls and provides more information about the ODBC components installed and in use on your system. It also introduces the concept of a file data source that can be shared or placed on a central server and used by any user who has the appropriate drivers installed. This new version of ODBC is fully aligned with both the American National Standards Institute (ANSI) and the International Standards Organization (ISO). It is also backwards compatible with previous versions of the ODBC API. For more information on ODBC 3.0, see ODBC in the online Help for Windows NT 4.0 Server or refer to the documentation included with the ODBC 3.0 SDK.

Fortezza Support

Service Pack 3 Beta provides client-side and server-side SSL support for Fortezza via the SChannel DLL.  When used in conjunction with a Fortezza cryptographic service provider (CSP), SChannel enables Fortezza data integrity, user authentication, and data confidentiality.  Fortezza CSPs can be obtained from Fortezza technology vendors.

1.2 Support for PowerPC-Based Systems

Microsoft is in the process of phasing out all Windows NT-related development for the PowerPC architecture. Because of this, there are no PowerPC files included in Service Pack 3 for Windows NT 4.0. Microsoft plans to continue providing technical support for customers who use Windows NT 4.0 on the PowerPC architecture.

2.0  Installation Instructions for the Windows NT Service Pack 3 Beta
Before Installing the Service Pack

Please close active debugging sessions before installing this Service Pack, otherwise the update program will be unable to replace system files in use.  If a file is in use, a dialog box appears, in which you can choose to cancel the installation or to skip the file copy.  We recommend you choose to cancel and run the update program selecting the uninstall option.  Close active sessions on the system and rerun Update.exe to install the Service Pack.

Also, it is recommended that you run the Emergency Repair Disk before updating your system with a Service Pack.

To install the Service Pack from a compact disc:
1.  Insert the Service Pack compact disc into the CD-ROM drive.
2.  At the Command Prompt, change to the drive letter associated with the CD-ROM drive.
3.  Change directory to i386 or ALPHA (depending upon whether you have an Intel or ALPHA CPU), and type UPDATE.
4.  Follow the instructions that appear on the screen.

To install the Service Pack from a network drive:
1.  At the Command Prompt, type the command to connect to the network drive on which the Service Pack files reside.
2.  Change the drive letter to that network drive.  
3.  Change directory to i386 or ALPHA (depending upon whether you have an Intel or ALPHA CPU), and then type UPDATE.
4.  Follow the instructions that appear on the screen.

2.1  Service Pack Uninstall
This Service Pack contains an uninstall feature that you use to remove the Service Pack from your system.  It will restore your system to its previous state; for example, if you install Service Pack 3 Beta on top of Service Pack 2, when you uninstall Service Pack 3 Beta, Service Pack 2 will be left on your system.

To enable the uninstall option, you must create an uninstall directory the first time you run Update.exe. To do this, when prompted, click "Yes, I want to create an Uninstall directory."  A subdirectory in your Windows NT directory will be created; this requires at least 60 MB of free space on the drive on which Windows NT is installed.

To uninstall the Service Pack, run Update.exe and click "Uninstall a previously installed Service Pack."  After your system has rebooted, the Update.exe program will have replaced the files updated by the Service Pack with the files from the previous installation and will have returned your registry settings to what they were before the Service Pack 3 was installed.

If you install any applications that require Service Pack 3 Beta or have bug fixes contained in Service Pack 3 Beta, performing an uninstall could adversely affect those applications.

3.0  User Notes
3.1 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 reapply the Service Pack after the repair is completed. This is because the Emergency Repair Disk repairs your system by restoring your original Windows NT 4.0 setup.  After the repair has completed, simply follow the Installation Instructions (section 2.0 above) to reapply the Service Pack.

3.2 Adding New Components to the System

If you change or add new software or hardware components to your system after you have applied the Service Pack, you need to reapply the Service Pack.  This is because the files taken from the original Windows NT 4.0 disk set may not be the same as the files on the Service Pack disk set.  You cannot install new components directly from the Service Pack media (such as a new keyboard or printer driver).  You must install new components from the original product media.

3.3 Installing Symbol Files from the Compact Disc

Each program file in Windows NT has a corresponding symbol file that is used to find the cause of kernel STOP errors. To install the symbol files corresponding to the new binaries in Service Pack 3 Beta, 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):


This will copy the Service Pack 3 Beta .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).

For more information about debugging on Windows NT, see Chapter 39, "Windows NT Debugger," in the Microsoft Windows NT 4.0 Workstation Resource Kit.

3.4 Remote Access Service PPP CHAP MD5 Authenticator Support

Service Pack 3 Beta provides limited PPP MD5-CHAP authenticator support to the Remote Access Server, which may be useful for small user-count environments using non-Microsoft PPP dial-in clients. The support is local to a given RAS server.  The MD5 account information is stored in the RAS server registry and is not integrated or synchronized with the User Manager account database.  Integrated support will appear in a later release, at which time this limited support may be removed.

The local MD5-CHAP authenticator is enabled by creating the MD5 key below and adding "account" subkeys of the form [<domain>:]<user>, with subvalue "Pw" containing the account password.  The ":" notation is used instead of "\" due to the syntax rules of registry keys.  The 'domain:' is optional and typically omitted.  MD5-CHAP will not be negotiated (old behavior) when the MD5 key does not exist (default).


3.5  Microsoft DHCP Server

This version of the Microsoft DHCP Server modifies the format of the DHCP database.  You should back up the contents of your %windir%\system32\dhcp directory prior to upgrading.

The address conflict detection feature can limit the throughput of Microsoft DHCP Server.  For improved performance, reduce the number of ping retries in the Server Properties dialog box.  This feature is disabled by default.

Address conflicts are indicated by the replacement of the machine name with "BAD_ADDRESS."  If a Unique Identifier is specified for the address in the Client Properties dialog box, then the address was declined by the client.  If the Unique Identifier is not specified, then the address conflict was detected by the DHCP Server.

Microsoft DHCP Server can be configured to set a client's default gateway equal to its IP address.  This causes the client to use the Access Resolution Protocol (ARP) for all IP addresses on the local subnet and is useful for routerless networks.  To enable this feature for all clients in a scope, add the following value to the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer\Subnets\a.b.c.d\SwitchedNetworkFlag=1 (REG_DWORD)

This version of Microsoft DHCP Server supports BOOTP clients.  BOOTP addresses currently must be reserved in advance by creating an IP address reservation. Future versions of Microsoft DHCP Server will be capable of leasing dynamic addresses to BOOTP clients.

BOOTP clients that do not specify the parameter request list option ( 55 ) can still retrieve the following options from this release of Microsoft DHCP Server:

1	Subnet Mask
3	Router
5	Name Server
12	Host Name
15	Domain Name
44	NetBIOS over TCP/IP Name Server
45	NetBIOS over TCP/IP Datagram Distribution Server
46	NetBIOS over TCP/IP Node Type
47	NetBIOS over TCP/IP Scope
48	X Window System Font Server
49	X Window System Display Manager
69	SMTP Server
70	POP3 Server
9	LPR Server
17	Root Path
42	NTP Servers
4	Time Server

In order to obtain other options, the client must specify option 55 in the BOOTP request.  DHCP Server will return the options in the order listed above.  DHCP Server will return as many options as will fit in response packet.

The activity log feature creates a text log file of all DHCP Server activity. The file is located at %windir%\system32\dhcp\dhcpsrv.log.  When the activity log feature is enabled this file will be kept open by DHCP Server while the Server is running.  To delete the activity log file you must first stop DHCP Server, using the command:


If available disk space becomes low, the activity log will pause until sufficient disk space becomes available.

You must also stop and restart the DHCP Service after enabling or disabling Logging, Superscope, or DHCP Decline support.

3.6 Manually Updating OEM Drivers

OEM drivers supplied on the CD-ROM are not automatically updated by the Service Pack installation process. You must manually copy these updated drivers into the drivers directory of your machine.  The Service Pack media contains a DRVLIB directory, with subdiretories for various components.  If you determine the file is already installed on your system, you should make a backup copy of the file and then copy the updated file from the appropriate directory to the directory where it is installed on your system.  The following updated drivers are available in this Service Pack:

Network Adapter Drivers

Compaq NetFlex-3 and Netelligent: from drvlib\netcard\netflx3\i386\netflx3.sys
Intel E100B (and clones): from drvlib\netcard\e100b\i386\e100b.sys
3Com 3C590,3C592,3C595,3C597: from drvlib\netcard\3c59x\i386\el59x.sys

5.0 Notes for Users of the 128-bit North American Version of Windows NT 4.0

All encryption-related components in this version of Service Pack 3 Beta are limited to exportable 40-bit cryptography. During installation, you will be prompted when an existing component on your system containing 128-bit encryption is about to be replaced by an updated component with 40-bit encryption. If you require 128-bit support, you should click "Skip" when prompted during Service Pack Setup. A 128-bit version of this Service Pack Beta is not available. We recommend that you install this beta on a computer that has 40-bit encryption.
