Access Components. These updates are available on the CD-ROM or as
part of the SP4 Full Download.

Internet Explorer 4.01 with Service Pack 1
The latest release of Internet Explorer
providing fixes for the top product support issues in Internet
Explorer 4.0x, including Year 2000 issues.
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
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 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.)
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
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
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.
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
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.
Performance and Security Update
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.
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.
Internet Naming Service (WINS)
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
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
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
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
NTFS Version 4 and NTFS Version 5 Support

read NTFS 5 volumes.
Windows Media Technologies
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.)

standard properties and methods. SP4 includes five new accessibility
applications programming interfaces (APIs).
