Ngày nay, trên toàn cầu đã có nhiều hệ điều hành mạng như Linux ,
WinNT và mới đây còn có công nghệ mới như Windows 2000 Server . Với
Windows 2000 của Microsoft ra đời hổ trợ một số tiện ích mà không có ở
những hệ điều hành Win9x và WinNT về việc điều khiển từ xa , việc cài
đặt hàng loạt các ứng dụng đến máy của những người dùng mạng từ một
vị trí trung tâm .
Chương 5 – Các Dịch Vụ Hệ Thống nằm trong bộ bài giảng Dịch vụ mạng. Bài giảng được biên soạn có nội dung giới thiệu về DHCP Dynamic Host Configuraton Protocol), RIS (Remote Installation Services), Terminal Services.
Chú ý : Nếu bạn chọn Remote Installation Services (RIS), RIS chủ (RIS server)sẽ cài đặt Windows 2000 lên RIS khách ( RIS clients). RIS server có khả năng thiết lập một trong hai kiểu “lựa chọn”: một là CD-Based, nó chỉ bao gồm duy nhất hoạt động hệ điều hành Windows 2000, hoặc là Remote Instalation Preparation (RIPrep) ở đây nó có thể bao gồm cả hệ điều hành Windows 2000 và các ứng dụng. RIS thường được sử dụng để tháo và cài đặt Windows 2000 Professional.
With over 1,000,000 copies of our MCSE, MCSD, CompTIA, and Cisco
study guides in print, we have come to know many of you personally. By
listening, we've learned what you like and dislike about typical computer
books. The most requested item has been for a web-based service that
keeps you current on the topic of the book and related technologies. In
response, we have created email@example.com, a service that
includes the following features
HiGain® provides HDSL repeaterless transport of T1 service over two unconditioned
copper pairs up to 12,000 ft on 24 AWG (0.5 mm), or 9,000 ft on 26 AWG (0.4 mm). HiGain
systems are used by service providers to enable high-speed data, voice and video
communications to their customers. ADC’s HiGain systems are designed with plug-and-play
compatibility that do not require the removal of bridged taps. Ease of installation enables
phone companies to respond to service orders in a matter of hours.
HiGain® doubler units (HDUs) allow HiGain systems to be used for applications outside the
Carrier Service Area (CSA), increasing the range by up to five times. Span equipment consists
of HDUs that can be deployed in the existing repeater enclosures or in remote enclosures for
higher deployment density and lower deployment costs. Enclosures are available for both
above- and below-ground installations.
Module 7: Installing, configuring, and troubleshooting the network policy server role service. This module explains how to install, configure, and troubleshoot the network policy server role service. Network Policy Server (NPS) is the Microsoft implementation of a Remote Authentication Dial-in User Service (RADIUS) server and proxy in Windows Server 2008. NPS is the replacement for Internet Authentication Service (IAS) in Windows Server 2003.
This white paper describes how to configure a test lab with five computers for testing Network Access Quarantine
Control and remote access certificate provisioning for computers not joined to a domain. This white paper offers
only step-by-step procedures, not a conceptual overview of all the required technologies.
Use the following strategy to present this module:
Introduction to the SMTP Service
Explain that SMTP is the Internet standard for e-mail message delivery.
Describe how the SMTP service works in IIS, and how the SMTP server
sends and receives e-mail messages. Explain that, if they did not enable the
SMTP service during Microsoft Windows® 2000 installation, they can
enable it by using Add/Remove Programs in Control Panel.
The Soneplex family of HDSL remote enclosures allows flexible
configuration of Soneplex HDSL type 400 remote modules.
Options include single and multiple installation, cabinet, telco
room or rack mounting, and inside or outside deployment.
ADC's Soneplex system is the lowest total cost solution for
carriers to grow their T1-based business services. Focused on
providing flexible, end-to-end solutions, the Soneplex system
saves carriers money on T1-based services over copper or fiber,
using HDSL, ADSL, traditional T1 repeater or Optical DS2
technology, in a single platform.
The HiGain HXU-359 STS-1 multiplexer is a cost-effective
SONET access platform that enables direct insertion of
DS1s or E1s onto any SONET network via an economical
STS-1 interface. This environmentally hardened unit enables
installation in a co-location cage or remote cabinet.
The HXU-359 condenses SONET technology into the
highest service density multiplexer that minimizes space,
power and heat dissipation requirements. The HXU-359
offers a mixed T1/E1 service of up to 28 DS1s or 21
E1s or any valid combination onto a single high-speed
STS-1 network interface....
The NCX-1000 is a passive fiber-to-the node (FTTN) service delivery cabinet that is easily placed in
the feeder or distribution plant to support any re-sectionalizing or broadband overbuild application.
It is typically installed with an adjunct DSLAM cabinet or remote terminal that houses a broadband
DSLAM. The compact cabinet is designed for FTTN applications where re-sectionalizing the
network requires either a new cross connect interface with a 1:2 ratio of feeder to distribution
pairs or for 1:1 ratios where ADC’s patented Distribution Intercept (DI) service delivery solution is
Standard security hardening procedures should be applied to the guest OS, including disabling unnecessary
network services, removing unnecessary packages, restricting remote root access, and enforcing strong
password policies. Use if possible a centralized authentication service such as Kerberos. Consider installation of
monitoring and intrusion detection tools.
It is possible to install additional applications and provision additional users on the cell OS instance, but it is
recommended that you do not do this—widening access to the cell OS may decrease security. ...
