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 3RPC TransportThis service pack includes new versions of the remote procedure call (RPC) run-time dynamic-link library (DLL) and the RPC subsystem service (Rpcss.exe). 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 installed on both the client machine and the server machine. You also need Beta 2 or later of MSMQ 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, and the new RPC header files and Microsoft Interface Definition Language (MIDL) compiler (available in the Win32 Software Development Kit). 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 Service Pack 3 SDK Help file (see "Win32 APIs and SDK for Service Pack 3" later in this file), or refer to the documentation in the upcoming MSMQ SDK. CryptoAPI 2.0 The Microsoft Cryptography application programming interface (CryptoAPI) provides developers with core cryptographic and certificate functions. CryptoAPI 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. CryptoAPI 2.0 (the upgrade contained in this service pack) includes this core cryptographic functionality as well as certificate-based functionality. Developers can use certificates with these public-key operations and perform the necessary encapsulations and encoding to apply certificates within their applications. CryptoAPI 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. Service Pack 3 provides one CSP (the Microsoft RSA Base Provider), which gives users and developers access to exportable cryptography. CryptoAPI 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 CryptoAPI to operate with other certificate-based systems that adhere to these standards. The release version of CryptoAPI 2.0 contains several updates to the developer's release version of September 1996, including both parameter changes and naming changes. These changes are reflected in the Crypt32.dll and Wincrypt.h files. Please consult the CryptoAPI 2.0 documentation for details. DirectX 3.0 Service Pack 3 contains a complete software implementation of DirectX 3.0 as well as ongoing hardware support for the DirectDraw component of DirectX 3.0. This translates into the following major feature changes since the release of DirectX 2.0 as supported in Windows NT 4.0: DirectDraw Access to all 256 entries in the palette when in exclusive mode. DirectSound Software-based 3-D localization of audio (Direct3DSound APIs.) DirectInput COM interface supporting mouse and keyboard data with documentation and sample programs. DirectPlay IDirectPlayLobby, an interface that allows an external application to launch a DirectPlay 3.0 application and provide it with all information necessary to connect to a session. Internet TCP/IP service provider for multi-player applications over the Internet. Direct3D Software emulation for the Direct3D 3.0 API. (In Windows NT 4.0, we provide a beta version of the software drivers for Direct3D 2.0.) ODBC 3.0 Service Pack 3 includes the latest version of Microsoft Open Database Connectivity (ODBC) API. ODBC 3.0 provides an updated ODBC Control Panel and an ODBC Administrator interface that uses tabbed controls and provides more information about the ODBC components installed and in use on your system. This updated version of ODBC also introduces the concept of a file data source that can be shared or placed on a central server. With the appropriate drivers installed, ODBC 3.0 will let a user share a file data source or place a file data source on a central server. This new version of ODBC adheres to the standards of both the American National Standards Institute (ANSI) and the International Standards Organization (ISO). It is also backward compatible with previous versions of the ODBC API. For more information on ODBC 3.0, refer to the documentation included with the ODBC 3.0 SDK. SMB Signing Service Pack 3 includes an updated version of the Server Message Block (SMB) authentication protocol, also known as the Common Internet File System (CIFS) file sharing protocol. The updated protocol has two main improvements: it supports mutual authentication, which closes a "man-in-the-middle" attack, and it supports message authentication, which prevents active message attacks. SMB signing provides this authentication by placing a digital security signature into each SMB, which is then verified by both the client and the server. In order to use SMB signing, you must either enable it or require it on both the client and the server. If SMB signing is enabled on a server, then clients that are also enabled for SMB signing will use the new protocol during all subsequent sessions and clients that are not enabled for SMB signing will use the older SMB protocol. If SMB signing is required on a server, then a client will not be able to establish a session unless it is enabled for SMB signing. SMB signing is disabled by default on a server system when you install the Service Pack; it is enabled by default on a workstation system when you apply the Service Pack. For information on how to configure SMB signing, go to the Microsoft Knowledge Base at http://www.microsoft.com/kb/ and search for the following article: Q161372 -- How to Enable SMB Signing in Service Pack 3. Note: SMB signing will not work with the direct host IPX protocol. This is because the direct host IPX protocol modifies SMBs in a way that is incompatible with signature-enabled SMBs. This incompatibility will be most obvious when you have direct host IPX clients and you require SMB signing on the server. Requiring SMB signatures on the server will cause the server to not bind to the direct host IPX interface, which will then force all connections to the server to be signed. If you disable the NWLink binding on the server then you will be able to use SMB signing. Also, SMB signing will impose a performance penalty on your system. Although it doesn't consume any more network bandwidth, it does use more CPU cycles on the client and server side. For more information on SMB signing, see the Microsoft FTP site at ftp://ftp.microsoft.com/developr/drg/CIFS/sec.htm. For general information on the CIFS protocol, see the Microsoft Web site at http://www.microsoft.com/intdev/cifs/. Password Filtering This Service Pack includes a password filter (Passfilt.dll) that allows system administrators to increase password strength. This filter is copied to %system root%\SYSTEM32 when the Service Pack is installed on the system. The password filter should be copied to the primary domain controller for the domain, and to any backup domain controllers in the event the server role in the domain changes. To use the password filter, the following registry entry must exist. If it doesn't exist you must create it. WARNING: Using the registry editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT. Microsoft cannot guarantee that any problems resulting from the use of the registry editor can be solved. Use this tool at your own risk. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa Value: Notification Packages Type: REG_MULTI_SZ Data: Passfilt.dll Notification Packages contains a list of DLLs to be loaded and notified of password changes and password change requests. You can audit the loading of Notification Packages by setting the audit policy in User Manager. To do this, start User Manager and then click Audit on the Policies menu. In the Audit Policy dialog box click Audit These Events and then enable Restart, Shutdown, and System by selecting the Success and/or Failure check boxes. Passfilt.dll implements the following password policy:
Restricting Anonymous User Access Windows NT has a feature where anonymous logon users can list domain user names and enumerate share names. Some customers who want enhanced security have requested the ability to optionally restrict this functionality. Service Pack 3 provides a mechanism for administrators to restrict the ability for anonymous logon users (also known as NULL session connections) to list account names and enumerate share names. In addition, Service Pack 3 has a feature that restricts anonymous logon users from connecting to the registry remotely. After Service Pack 3 is installed, anonymous users cannot connect to the registry and cannot read or write any registry data. Also, a new built-in group known as Authenticated Users is created when you install Service Pack 3. The Authenticated Users group is similar to the Everyone group, except for one important difference: anonymous logon users (or NULL session connections) are never members of the Authenticated Users group. For more information on these new features, including information on configuring the registry to restrict anonymous user access to list domain user names and enumerate share names, go to the Microsoft Knowledge Base at http://www.microsoft.com/kb/ and search for the following article: Q143474. Using a System Key to Strongly Encrypt Password Information Service Pack 3 provides the capability to use strong encryption techniques to increase protection of account password information stored in the registry by the Security Account Manager (SAM). Windows NT stores user account information, including a derivative of the user account password, in a secure portion of the registry protected by access control and an obfuscation function. The account information in the registry is only accessible to members of the administrators group. Windows NT, like other operating systems, allows privileged users who are administrators access to all resources in the system. For users who require enhanced security, strong encryption of account password derivative information provides an additional level of security to prevent administrators from intentionally or unintentionally accessing password derivatives using registry programming interfaces. The strong encryption capability in Service Pack 3 is an optional feature. Strong encryption protects private account information by encrypting the password data using a 128-bit cryptographically random key, known as a password encryption key. Administrators may choose to implement strong encryption by defining a system key for Windows NT. To do this, administrators can run a utility called Syskey.exe. For more information on using Syskey.exe to configure a system key, go to the Microsoft Knowledge Base at http://www.microsoft.com/kb/ and search for the following article: Q143475. Win32 APIs and SDK for Service Pack 3 Service Pack 3 includes several new APIs, including two Win32 APIs pertaining to spin counts on critical sections (InitializeCriticalSectionAndSpinCount() and SetCriticalSectionSpinCount()). To develop applications that take advantage of these new APIs, a Service Pack 3 SDK will be available on the Microsoft Web site at: http://www.microsoft.com/msdn/sdk
1.2 Support for PowerPC PlatformMicrosoft 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.
1.3 Downloading and Extracting the Service PackIf you have downloaded this Service Pack from an FTP site or a Web site, you should read the release notes completely before you extract and install the Service Pack.After downloading the Service Pack, you will have a compressed executable file (for example, nt4sp3_i.exe) on your hard drive. To extract this file and begin the installation process, type nt4sp3_i.exe at the Command Prompt or double-click the file from NT Explorer. You can also extract the file into the current directory without launching the installation program by using the Command Prompt switch /x (for example, at the Command Prompt, type nt4sp3_i /x).
2.0 INSTALLATION INSTRUCTIONS FOR WINDOWS NT 4.0 SERVICE PACK 3
2.1 Before You Install the Service PackClose all active debugging sessions before installing this Service Pack, otherwise the Update program will be unable to replace system files that are in use. If a file is in use when you install the Service Pack, a dialog box will appear in which you can choose to cancel the installation or skip the file copy. We recommend you choose to cancel the installation, and then run Update.exe again, being sure to select the uninstall option. Close all active sessions on the system, and then run Update.exe again to install the Service Pack.Also, to maximize the ability to recover the system in the event of installation failure, it is recommended that you do the following before installing the Service Pack:
files.3. Disable any non-essential third-party drivers and/or services (that is, drivers and services that are not required to boot the system).4. Contact the original equipment manufacturer (OEM) that provided the driver or service for the updated versions of the file(s).If you have installed a pre-release version of Microsoft Internet Explorer 4.0 prior to installing this Service Pack, you must remove the pre-release version of Internet Explorer 4.0 from your computer before you install the Service Pack. You may then reinstall Internet Explorer after successfully completing the Service Pack 3 installation. This will not be necessary with the retail release of Internet Exporer 4.0. Upon retail release, Microsoft Internet Explorer 4.0 will be made available to customers on the Microsoft Web site. Users of NEC Versa 6050 or 6200 Series notebook computers that shipped preinstalled with Windows NT version 4.0 should select "Yes" when Service Pack 3 update.exe prompts you to replace the hal.dll file. If you are running SystemSoft's CardWizard for Windows NT (support for PCMCIA) or PowerProfiler for Windows NT (support for Advanced Power Management), you must complete critical pre-installation procedures prior to installing this Service Pack. Otherwise, your computer may no longer boot after installation of Service Pack 3. These procedures can be found in the product section at http://www.systemsoft.com. Advanced Power Management is not supported by Windows NT version 4.0. As a result, Microsoft recommends that you remove Advanced Power Management features before installing this Service Pack.
2.2 Installing the Service PackTo install the Service Pack from the compact disc:
compact disc, click Windows NT Service Pack, and then
click Install Service Pack.
3. When you are asked whether you want to open the file
Spsetup.bat or save it to disk, click Open and then follow
the instructions that appear on the screen.
Note: To use the uninstall feature of this Service Pack,
you must create an Uninstall directory during the initial
installation. Also, if you are reapplying the Service
Pack after installing new software or hardware, you must
choose to create a new uninstall directory. To indicate
this, you must click "Yes, I want to create an Uninstall
directory" when you are prompted. For further information,
see Section 2.3 and 3.2.
the compact disc, open the Command Prompt window and change
the directory to the drive letter associated with the
CD-ROM drive.
5. Change the directory to \i386 or \ALPHA (depending
upon whether you have an Intel or ALPHA CPU), and type UPDATE.6. Follow the instructions that appear on the screen.
Note: To use the uninstall feature of this Service Pack,
you must create an Uninstall directory during the initial
installation. Also, if you are reapplying the Service
Pack after installing new software or hardware, you must
choose to create a new uninstall directory. To indicate
this, you must click "Yes, I want to create an Uninstall
directory" when you are prompted. For further information,
see Section 2.3 and 3.2.
To install the Service Pack from a network drive:
upon whether you have an Intel or ALPHA CPU), and
then type UPDATE.
4. Follow the instructions that appear on the screen.
Note: We recommend that you choose to create an Uninstall
directory the first time you install the Service Pack. Also,
if you are reinstalling the Service Pack after installing new
software or hardware, you must choose to create a new
Uninstall directory. To indicate this, click "Yes, I want
to create an Uninstall directory" when you are prompted.
For further information, see Section 2.3 and 3.2.
2.3 Service Pack UninstallThis Service Pack contains an uninstall feature that you can use to restore your system to its previous bootable state.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 return your system to a previous bootable state, run Update.exe and click "Uninstall a previously installed Service Pack." After your system has restarted, the Update.exe program will replace the files updated by the Service Pack with the files from the previous installation and will return your registry settings to what they were before Service Pack 3 was installed. Note: If you install any applications that require Service Pack 3 or have bug fixes contained in Service Pack 3, performing an uninstall could adversely affect those applications. Note: If you plan to install an older service pack after uninstalling Service Pack 3, take note of the following important precaution. Service Pack 3 modifies the Security Account Manager (SAM) database such that older versions of the SAMSRV.DLL and WINLOGON.EXE files no longer recognize the database structure. Therefore, the uninstall process does not restore these files when uninstalling Service Pack 3. If you install a prior service pack (e.g., Service Pack 2) after uninstalling Service Pack 3, click "No" on the "Confirm File Replace" dialog boxes that ask if you wish to overwrite SAMSRV.DLL and WINLOGON.EXE. If you overwrite the newer files with their older versions, you will be unable to logon to the system.
3.0 USER NOTES
3.1 Emergency Repair DiskIf you use the Windows NT Emergency Repair Disk to repair your Windows NT system at some time after you install the Service Pack, you will need to reinstall 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) to reinstall the Service Pack. For more information on using the Windows NT Emergency Repair Disk utility, go to the Microsoft Knowledge Base at http://www.microsoft.com/kb/ and search for the following article: Q146887.Note: To use the Emergency Repair Disk utility, you must have the updated version of Setupdd.sys. The updated version is contained in Service Pack 3. To update your version of Setupdd.sys, copy Setupdd.sys from the Service Pack to your setup boot disk #2. This will replace the older version of Setupdd.sys with the updated version. For more information, go to the Microsoft Knowledge Base at http://www.microsoft.com/kb/ and search for the following article: Q158423.
3.2 Adding New Components to the SystemIf you change or add new software or hardware components to your system after you have installed the Service Pack, you need to install the Service Pack again. 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 and then reinstall the Service Pack.For example, if you install the SNMP service after installing Service Pack 3, you will need to reinstall the Service Pack. If you fail to do so, you will receive the error "Entrypoint SnmpSvcGetEnterpriseOID could not be located in snmpapi.dll." This is because some of the files in the SNMP service have been updated in the Service Pack and you have a version mismatch. Reinstalling the Service Pack fixes the problem by copying the newer versions of the files to your system. Note: If you are reinstalling the Service Pack after installing new software or hardware, you must choose to create a new uninstall directory. To indicate this, click "Yes, I want to create an Uninstall directory" when you are prompted.
3.3 Installing Symbol Files from the Compact DiscEach 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, 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). 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 SupportService Pack 3 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 benegotiated (old behavior) when the MD5 key does not exist (default). HKLM\SYSTEM\CurrentControlSet\Services\RasMan\PPP\CHAP\MD5 [<domain>:]<user>(REG_SZ)Pw
3.5 Microsoft DHCP ServerThis 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 Address 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: NET STOP DHCPSERVER 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 Unencrypted Passwords No Longer Sent by DefaultConnecting to SMB servers (such as Samba and LAN Manager for UNIX) with an unencrypted (plain text) password fails after upgrading to Windows NT 4.0 Service Pack 3. This is because the SMB redirector in Service Pack 3 handles unencrypted passwords differently than previous versions of Windows NT. Beginning with Service Pack 3, the SMB redirector will not send an unencrypted password unless you add a registry entry to enable unencrypted passwords. For information on how to modify the registry, search the Microsoft Knowledge Base at http://www.microsoft.com/kb/ for the following article: Q166730. This article also contains information on how to change the Service Pack setup process so that unencrypted passwords are enabled after the Service Pack is installed.

Q150734 List of Bugs Fixed in Windows NT Version 4.0 5.0 ADDITIONAL FIXES AND WORK-AROUNDS
5.1 Tape Drive Not Recognized by Windows NTIn some instances, after you apply the Service Pack, Windows NT will not be able to load the drivers for a tape drive, which may cause the tape drive to shut down or be inoperable. This is due to a conflict between the ATAPI driver that controls IDE devices and the tape drive controller. To fix the problem, you must set your tape drive controller to a different I/O address.In most circumstances, your tape drive controller will be set to use an I/O address in the range 0x3F0-0x3F8. The ATAPI driver uses I/O address 0x3F6. If your tape drive controller has been assigned to 0x3F6, then you must assign the tape drive controller to an available address.
5.2 File Sharing Problems with Windows 95In some instances, you may experience "out of memory" problems when you save a file to a shared folder on a Windows 95 machine. You can obtain a fix for this problem at the following Microsoft Web site:http://www.microsoft.com/visualc/download/mfc42cab.htm
5.3 Reinstalling Hilgraeve HyperTerminal Private EditionService Pack 3 contains updates to the HyperTerminal product that shipped with Windows NT 4.0. If you have installed the Private Edition of HyperTerminal from Hilgraeve, Inc., then you need to reinstall the Private Edition after applying Service Pack 3. For more information on installing the Private Edition, go to the Microsoft Knowledge Base at http://www.microsoft.com/kb/ and search for the following article: Q162469.
5.4 Restoring Active Files and the Registry from TapePrior to Service Pack 3, the tape backup utility that shipped with Windows NT 4.0 would not restore active files if the registry was also restored. If you want to restore both the registry and active files, then you must use the version of ntbackup.exe that is included in Service Pack 3 (or newer).To restore the registry and active files from a tape backup:
the Service Pack CD.3. Run ntbackup.exe and restore the registry and system files from tape.4. Reboot the system when restore is complete.
5.5 LPR PrintingLPR printer ports are by default now limited to using 11 TCP/IP ports (721-731) to be RFC compliant. You can change this to have LPR use any TCP/IP ports greater than 1024 by changing a registry setting. For information on configuring the registry for LPR printing, search the Microsoft Knowledge Base at http://www.microsoft.com/kb/ for the following article: Q141708.
5.6 Updating Audio DriversIf you are not receiving audio from a Crystal Semiconductor audio chip or a Creative Labs Sound Blaster AWE32 PnP Wavetable Synthesizer, you might have to install the updated drivers for these devices. For detailed information on updating these drivers, go to the Microsoft Knowledge Base at http://www.microsoft.com/kb/ and search for the following article: Q143155.
6.0 NOTES FOR USERS OF THE 128-BIT VERSION OF WINDOWS NT 4.0All encryption-related components in this version of Service Pack 3 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 the "Skip" button on the dialog box when prompted during Service Pack setup. A version of this Service Pack with 128-bit encryption is available on request. See the following ordering information.Microsoft Internet Explorer supports both 40-bit and 128-bit encryption depending on the version (40-bit or 128-bit) of the file Schannel.dll. If you accidentally overwrite the 128-bit version of Schannel.dll with the 40-bit version included in this Service Pack, you can copy the original from your Windows NT Version 4.0 compact disc into the windir%\system32 directory to restore it. 7.0 HOW TO OBTAIN THE NORTH AMERICAN (128-BIT) VERSION OF SERVICE PACK 3The North American (128-bit) version of Service Pack 3 is intended for distribution only in the United States and Canada. Export of the North American version of this Service Pack from the United States is regulated by the International Traffic in Arms Regulations (ITAR, 22 CFR 120-130) of the U.S. State Department, Office of Defense Trade Controls.
