  4. Intranet Business Value • Reduce IT complexity and cost • Easier to develop, administer, and extend • MS Internal SAP application developedapproximately 30% quicker using “Intranet” • Integrated access point for all corporate information • Merging of private and public networks • Increased productivity • Simple content creation and publishing • Workgroup sharing and collaboration

  5. Intranet Business Value The Internet Explorer Advantage • Intranet Content - The broadest set of tools for creating Intranet content • HTML, Programming and Scripting Languages, Document Standards • Integrated Security • New Communication Tools • Personalization • IEAK for hands-free installation & ongoing management • Cross Platform

  6. Intranet Content HTML & multi-media Support • Broadest support for HTML standards including 3.2 • Stylesheets • Common look and Feel for Intranet • Easily managed • In-Line Sound & Video • Active Movie • Format independent • Open to new streaming formats

  7. Browser Container Active Document (e.g. Excel, Word) Intranet Content Leverage Existing Documents

  8. Browser is also generic container Active Document (e.g. Excel, Word) Active DocumentsAny Format - Leverage Existing Documents

  9. Components Components Graphics Sound Animation ... The Active Platform BackOffice Tools Active Desktop Active Server HTML HTML Scripting Scripting System services System services Component services Active Directory Storage Mgmt Security Network Standard protocols including ActiveX

  10. The Active Server HTML Hides the complexity of server programming and integrates components with system services Scripting Components System Services • Integrates components with • Active Server Pages • Active Directory • Data Access • Transaction Server • Collaboration Standard Protocols

  11. Windows NT 4.0Built-in Internet Server 2.0 • Web (HTTP), Gopher, and FTP publishing • Fully integrated with NTS 4.0 installation • Fastest Windows NT-based Web server • IIS 2.0 Dramatically improved performance • Security build in • Windows NT security • Secure key management • Enables Web-based client/server applications • Server-side business processes via ISAPI • Direct ODBC database access via IDC • FrontPage web site management tool

  12. WINS Server DNS Client • sales? • Lookup sales.arcadia.com • 157.55.94.89. • 157.55.94.89. DNS Name ServicesInternet-compatible DNS Server • Maps TCP/IP addresses to friendly machine names • Easy administration via DNS Manager • Dynamic and reliable name services via WINS integration

  13. Tunnel Point-to-Point Tunneling ProtocolVirtual Private Networks Corporate LAN Domain authentication INTERNET Encrypted PPP Packets Firewall Encapsulated encrypted PPP Packets Windows 95, Windows NT, any PPP connection Internet Service Provider Windows NT Server RAS • Enables low cost, secure remote access via the Internet • Provides data encryption for secure communications • Business Benefit: Enables corporations to out-source dial-up network access - users make a local call for remote access

  14. Internet Information Server 3.0 • Active Server Pages: (“Denali”) Integrated Web scripting and components for rapid server application development • Easy, open, compile-free, browser-neutral • NetShow: live & on-demand streaming media services • Index Server: scaleable, extensible content indexing • Crystal Reports: usage analysis • SSL v3: including client authentication support • Java VM: high-performance VM for development of ActiveX Server Components in Java • Front Page Extensions: “Point-and-publish” content management services
