Activity 13-4: Viewing and Configuring the Master Properties of the WWW Service Objective: To explore the use of master properties through the configuration of the WWW service From the open IIS Manager window, open the Web Sites folder properties Configure the folder properties as directed Test setting inheritance by viewing the Default Web Site properties 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

Creating and Configuring Web-Site Virtual Servers A virtual server is a unique Web site that behaves as if it were on a dedicated server IIS can support many virtual servers on a single server Configuration conflicts are avoided by identifying the IP address, TCP port, and host header name of each Web site and ensuring that the site is uniquely identified through these features 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

Activity 13-5: Creating a New Web Site Using the Web Site Creation Wizard Objective: To become familiar with the Web Site Creation Wizard Change the port number of the Default Web Site as directed and verify the change Create a new Web site using the Web Site Creation Wizard Create a default HTML index page for the new site 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

Configuring Authentication for Web Sites Authentication is the determination of whether or not a user account has the proper permissions to access a resource such as a Web site IIS provides five levels of authentication: Anonymous access Basic authentication Digest authentication Integrated Windows authentication .NET Passport authentication 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

Anonymous Access and Basic Authentication Users do not need to provide a user name and password Uses the IUSR_servername user account to provide authentication credentials Basic authentication User is prompted to supply a user name and password User needs a valid Windows Server 2003 user account One drawback is that information is transmitted using unencrypted Base64 encoding (easy to hack) 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

Digest Authentication and Integrated Windows Authentication Similar to basic authentication but hashes user name and password using MD5 algorithm Has specific software and Active Directory requirements Integrated Windows authentication Does not prompt for password Uses client’s logged on credentials Used primarily for internal intranets, has specific permissions requirements 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

.NET Passport Authentication and Multiple Authentications New method currently in testing to use the .NET Passport service Will require preproduction tests and a registration process If multiple authentication methods are configured, specific rules apply concerning precedence and applicability 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

Configuring Server Certificates and Secure Sockets Layer The Secure Sockets Layer (SSL) protocol encrypts Web traffic between a client and a Web server Configured from the Directory Security tab of the properties of a Web site Users access a secure server using https:// prefix SSL requires a server certificate from a certificate authority or from installed certificate services 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

Configuring FTP Virtual Servers The File Transfer Protocol (FTP) is used for file transfers between computers running TCP/IP FTP service is included with IIS 6.0 FTP uses two ports (TCP ports 20 and 21) Port 21 carries connection initiation and diagnosis information Port 20 carries data FTP uses Transmission Control Protocol (TCP) Connection-based protocol, session precedes data transfer 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

File Transfer Protocol Features of TCP include: Sending computer waits for an acknowledgement and retransmits data if it is not received Packets are assigned a sequence number Packets contain a checksum for ensuring integrity FTP requires a server running FTP server software and clients must run FTP client software There are many free and shareware utilities that can be downloaded for running FTP 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment

Configuring FTP Properties Multiple FTP sites can be configured on a single IIS 6.0 server Each site operates independently and runs transparently Each site has property sheets that can be customized independently 70-290: MCSE Guide to Managing a Microsoft Windows Server 2003 Environment
