Welcome to Microsoft® Proxy Server. Microsoft Proxy Server provides an easy, secure way to bring Internet access to every desktop in an organization.

Microsoft Proxy Server supports all Internet protocols, including WWW (HTTP), FTP, RealAudio (streaming audio), VDOLive (streaming video), IRC (Internet Relay Chat), and mail and news protocols. Support for Novell’s IPX/SPX transport means that deployment of TCP/IP on a private network is unnecessary. Internet sites can be accessed by Web browsers running on any operating system, and by all 16-bit and 32-bit Windows® Sockets applications, with no modifications to the applications.

Microsoft Service Advantage

Microsoft Service Advantage provides large organizations with the services and support they need to successfully plan, build, and manage mission-critical systems based on Microsoft products. Microsoft Service Advantage combines direct services from Microsoft with those from established enterprise service partners, providing a total solution that delivers real business advantage.

Direct Services

Microsoft offers the following direct services for global enterprise organizations: Enterprise Program Manager, Premier, Premier Global, Custom Consulting, Technology Consulting Blueprints, and the Microsoft Solutions Framework. All can be purchased with a single Microsoft Master Service Agreement.

An Enterprise Program Manager is an on-site, senior-level consultant who combines high-level architectural expertise with a long-term commitment and in-depth knowledge of your organization, tailoring specific guidance to the way your organization uses technology.

Premier support services help you achieve smooth, stable systems deployments with maximum uptime. Premier includes a designated support team who gets to know your technical environment and works with you to provide proactive services to help avoid problems before they occur. You also get reactive support—24-hours-a-day, 7-days-a-week direct access to senior support engineers—to minimize unplanned downtime.

Premier Global extends Premier support for multinational organizations. Premier Global helps you with worldwide systems deployment by coordinating both proactive and reactive Premier support services across country/regions boundaries.

Custom Consulting, delivered by Microsoft Consulting Services, helps you plan, build, and manage distributed computing environments, with a strong emphasis on knowledge transfer—empowering you to become proficient with Microsoft technology. Highly skilled in client-server architecture and design, Microsoft consultants frequently serve in a project-management capacity, helping to ensure a quality implementation by working closely with both you and your third-party partners.

Technology Consulting Blueprints are predefined consulting projects around specific technology topics, such as Windows 95 and Office 95 migration planning, Microsoft Exchange planning, and Internet/Intranet application planning. These represent Microsoft Consulting Services’ best practices in areas critical to large organizations. As a result, the general requirements, deliverables, approach, and expectations are well defined in advance, with the implementation specifics tailored to each organization.

Microsoft Solutions Framework (MSF), developed from years of product development and customer experience, is a process guide for planning, building, and managing technology projects. MSF delivers a suite of concepts and reference models that help you identify effective team structures, a dynamic development and life cycle model, and flexible application architecture. It is available in facilitated training from Microsoft Solution Provider ATECs and Microsoft, and includes a CD-ROM knowledge base.

You can contact your subsidiary to find out whether the type of products and services described in this appendix are available in your area.

Microsoft Services for People Who Are Deaf or Hard-of-Hearing

Sales Information

You can contact Microsoft Sales Information Center on a text telephone by dialing (800) 892-5234 between 6:30 A.M. and 5:30 P.M. Pacific time.

Customizing Windows or Windows NT

There are many ways you can customize Windows or Windows NT to make your computer more accessible.

• Beginning with Windows 95, accessibility features are built in to Windows. These features are useful for individuals who have difficulty typing or using a mouse, have moderately impaired vision, or who are deaf or hard-of-hearing. The features can be installed during setup, or you can add them later from your Windows 95 installation disks. Look up “accessibility” in the Windows Help Index for information about installing and using these features.

• Many of the features which make Windows 95 more accessible can be added to Windows NT, earlier versions of Microsoft Windows, and MS-DOS through Access Packs. You can download these files by modem, or you can order them on disks from Microsoft.

• You can also use Control Panel and other built-in features to adjust the appearance and behavior of Windows or Windows NT to suit varying vision and motor abilities. These include adjusting colors and sizes, sound volume, and the behavior of the mouse and keyboard.

• Dvorak keyboard layouts make the most frequently typed characters on a keyboard more accessible if you have difficulty using the standard “QWERTY” layout. There are three Dvorak layouts: one if you are a two-handed user, one if you type with your left hand only, and one if you type with your right hand only. You do not need to purchase any special equipment to use these features.

The specific features available, and whether they are built-in or must be obtained separately, depend on which operating system you are using.

For full documentation on the accessibility features available in the operating system you are using, obtain the appropriate application notes listed below. Accessibility features are also documented in the Microsoft Windows 95 Resource Kit and the Microsoft Windows NT Resource Kit.

Which Files to Download or Order

You can obtain these files by downloading them with your modem, or you can order them on disks by phone. Specific information about downloading or ordering these files immediately follows this list of files.
