The latest release of Internet Explorer providing fixes for the top product support issues in Internet Explorer 4.0x, including Year 2000 issues.

Management Enhancements

Windows Management Instrumentation

Windows Management Instrumentation(WMI) provides a bi-directional instrumentation access mechanism. It brings together the management data from the hardware platform, drivers and applications and passes the consolidated data into a consistent management information store. This store, developed to conform to the requirements of the Web-Based Enterprise Management (WBEM) proposals, uses the Desktop Management Task Force (DMTF) and Common Information Model (CIM) as the basis for exposing and interacting with this information. CIM and WMI are enabling technologies. Together these core technologies provide a powerful and consistent mechanism enabling management applications, platforms and consoles to perform a wide variety of management tasks on Windows-based hardware and software. (Available on CD-ROM only)

User Profile Quotas

The Proquota.exe is a utility that can be set up to monitor the size of users' profiles. If an individual user's profile exceeds the predetermined file limit, the user won't be able to log off of the computer until the user reduces the size of the file.

Event Log Service

SP4 contains new features in the Event Log Service to assist how administrators measure the reliability and availability of Windows NT. The SP4 Event Log Service records three new events in the system event log that are useful in measuring operating system availability:

  • Clean shutdown event.
  • Dirty shutdown event.
  • System version event.

Security Enhancements

Security Configuration Manager (SCM)
Security Configuration Manager (SCM) allows administrators to define and apply security configurations for Windows NT Workstation and Windows NT Server installations. SCM can also inspect installed systems to locate any degradation in system security. (Available on CD-ROM only or as a separate download.)

NTLMv2 Security

SP4 contains an enhancement to NTLM security protocols called NTLMv2, which significantly improves both the authentication and session security mechanisms of NTLM.

Secure Channel Enhancements

SP4 contains an enhancement to the secure channel protocols used by member workstations and servers to communicate with their domain controllers and by domain controllers to communicate with other domain controllers. In addition to authentication, you can now encrypt and check the integrity of these communications.

Event Log Security Privilege

SP4 includes a fix in the Event Log service that requires that the Security privilege be enabled in order to view and manage the security event log. This change enforces the security policy that administrators need to be granted the privilege to manage the security log--they won't be able to manage the log simply because they are members of the Administrators group.

Networking Enhancements

TAPI 2.1

SP4 includes a new user version of Windows Telephony Services, TAPI 2.1, making it easier and less expensive for organizations to deploy client/server telephony applications in call centers and other areas.

Microsoft Routing and Remote Access Service

Microsoft® Routing and Remote Access Service (RRAS) provides advanced routing and internetworking capabilities. It provides branch offices, departments, and small businesses with routing, remote access, and virtual private network (VPN) capability all in one easy-to-manage service. If RRAS is already installed, SP4 will update your system to RRAS Hotfix 3.0 components automatically.

PPTP Performance and Security Update

New performance and security updates to the Point to Point Tunneling Protocol (PPTP) that greatly increases data transfer speed and enhances security. The PPTP client and server system must both be running the updated files to get the new benefits.

DCOM/HTTP Tunneling

This update allows DCOM client/server communication to cross firewalls over the HTTP protocol port. The new protocol "Tunneling TCP" is used like other DCOM protocols. The benefits of Tunneling TCP include high performance, use of existing open ports in the firewall, and control of client access for proxy administrators.

Windows Internet Naming Service (WINS)
Windows NT Server includes the following new Windows Internet Naming Service (WINS) and WINS Manager features:

  • Manual removal of dynamic WINS database records.
  • Multi-select operations for WINS database records.
  • Burst mode handling for WINS servers.

Dynamic Host Configuration Protocol (DHCP)
This Service Pack includes several quality improvement fixes to correct known Dynamic Host Configuration Protocol (DHCP) issues reported for Microsoft® DHCP Server, the DHCP Manager administration tool, and for Microsoft DHCP-enabled clients running under earlier released versions of Windows NT 4.0

Remote Winsock (DNS/Port 53)
Proxies or firewalls will often disable the Domain Name System (DNS) port number 53 in order to deter external sites from querying the internal DNS structure. As a result, inbound response packets sent on port 53 can't be received. SP4 provides a solution to change the Windows NT DNS server port number and configure it to use a different port number when connecting outbound.

Internet Group Management Protocol (IGMP) v2
IGMPv2 allows a computer to inform the router that it's leaving a group. This update enables the router to determine if there are no more members in a group and then executes a command to stop forwarding multi-cast packets on to the link. This update is useful when users are frequently joining and leaving groups.

Interoperability Enhancements

Microsoft File and Print Service for NetWare Support for Client32
Microsoft File and Print Services for NetWare (FPNW) permits Windows NT 4.0 Server to act as a NetWare 3.X Server and is able to process file and print requests from NetWare clients without changing or updating the NetWare client software. This Service Pack provides an update that allows Windows NT 4.0 to support NetWare's Client32. This update installs only on those computers that have the FPNW service already installed.

NTFS Version 4 and NTFS Version 5 Support
There are two recent versions of Windows NT File System (NTFS):

  • version 4 - supported by both Windows NT 3.51 and Windows NT 4.0
  • version 5 - supported by Microsoft® Windows® 2000 Server

This Service Pack contains an updated version of NTFS.sys that can also read NTFS 5 volumes.

Windows Media Technologies

Microsoft Windows NT Server NetShow Services
SP4 contains an updated version of NetShowTM Services enabling Internet service providers (ISPs) and organizations to deliver high quality audio and video at every bandwidth across the Internet or enterprise networks. This release of NetShow Services features greatly enhanced audio and video that offers a high quality experience. Simplified setup, configuration, and administration of the NetShow server components and tools give ISPs a reliable and cost-effective platform for hosting large amounts of content. (Available on CD-ROM only or as a separate download.)

Microsoft Windows Media Player
Microsoft® Windows® Media Player replaces Microsoft® ActiveMovie as well as the Microsoft® NetShow Player. Windows Media Player has all the features found in both of the other multimedia players, plus many more. It also upgrades existing Windows Media Player and ActiveMovie support to provide convenient access to new Windows Media content. Windows Media Player supports most local and streaming multimedia file types including WAV, AVI, QuickTime, RealAudio 4.0 and RealVideo 4.0. (Available on CD-ROM only or as a separate download.)

Application Services Enhancements

Active Accessibility Support
Microsoft® Active Accessibility (MSAA) is a COM-based standard method by which a utility program interacts with an application's user interface (UI). Using MSAA applications can expose all UI elements and objects with standard properties and methods. SP4 includes five new accessibility applications programming interfaces (APIs).

Remote Procedure Call Enhancements for Visual Basic
RPC enhancements for VB have been provided to support a User Data Type (UDT) allowing the TypeLib arrangement of structures. The new interfaces provide UDT information and a UDT field for the Access Database.

Visual Studio-MICS
This Service Pack includes an update to Visual Studio called Visual Studio Analyzer Events. Visual Studio Analyzer Events provides a graphical representation of high-level behaviors and their solutions. Use Visual Studio Analyzer Events to view graphically simple tables of event logs, the system's performance, and Windows NT Performance Monitor, as well as other system data.

Other Enhancements

Compaq Fiber Storage Driver
When installed, the Compaq fiber storage driver provides support for Compaq fiber storage devices. The certified devices are:
  • Compaq Fiber Channel Host Controller/P for PCI.
  • Compaq Fiber Channel Host Controller/E for EISA.
(Available on CD-ROM only.)
