Provides Quality of Service (QoS) services for None. streaming audio and video over IP networks. Primarily used for home networks; on Server platforms qWAVE provides only rate-of-flow and prioritization services. Remote Assistance is used to provide interactive None. technical support. The Remote Assistance feature provides functionality for both the user requesting support and the person providing it. Used to transfer only deltas of files across a network. A collection of tools for managing other servers remotely. Remote Server Administration Tools include support for managing most roles and six features without installing the related role or feature. These tools are also available for download on download.microsoft.com so that you can install them on Windows Vista. None. Dependencies differ depending on which roles and features you want to support. The Web Server (IIS) Tools require the Windows Process Activation Service feature. The BITS Server Extension Tools require the Web Server role and Windows Process Activation Service feature. The SMTP Server Tools require the Web Server role. None.

<webSiteAdministrationTool> Contains information about the location and the structure of the Web Admin tool (WebAdmin.axd). You can use this section to add new toolbar buttons and new features to administer.

Supports the ability to tunnel Remote Procedure Web Server role and Call (RPC) connections through Hypertext Windows Process Transport Protocol (HTTP) and HTTPS Activation Service feature. connections. This feature is used, for example, to provide Outlook Anywhere access, enabling users of Microsoft Office Outlook to work against a Microsoft Exchange Server from anywhere on the Internet. Although this may sound like a security problem, done properly it can significantly enhance network security.

We ll conclude the chapter by looking at the new health monitoring API, which is a diagnostic tool for ASP.NET.

Part III:

The health monitoring API in ASP.NET 2.0 gives the system administrator and the members of the operational staff of a Web site tools for monitoring the health of the system. The ability to rapidly diagnose failing operations or broken subsystems is crucial to maintaining the performance of a Web site.

Table 11-2 Features Included in Windows Server 2008 Feature Name Description The vast majority of VPN connections are used almost exclusively for e-mail access, yet they provide the user with complete access to the corporate network. By exposing only RPC over HTTP and enabling users to connect using Microsoft Outlook, the organization eliminates the need for many of these VPN connections, significantly reducing the risk that malware will enter the organizational network over a VPN connection. Simple TCP/IP services Originally designed to troubleshoot TCP/IP None. connections in the days when those were very unreliable, today the Simple TCP/IP services have no place in a network. The services include a character generator, daytime, discard (a service that takes any input and simply ignores it), echo, and quote of the day. If these services are installed, an attacker can very simply disable all network operations on a host by piping output from the character generator into the echo service. Provides mail transport services and relays. Web Server role and Remote Server Administration Tools. None. Role Dependencies

Includes a POSIX subsystem. A set of Unix tools, None. including a bash shell, are available for download from Microsoft. A Telnet client for remote command-line access None. to Telnet servers. A Telnet server. It is highly recommended that you do not install and use this. Telnet is a clear-text protocol and is deemed highly insecure unless the channel is encrypted. Use Terminal Services instead. None.

The health monitoring API enables real-time tracing of running applications and provides statistics about usage and performance. The API s two main features are customizable analysis and automated notification of problems.

Now that we have completed our requirement-gathering process and developed the analysis architecture, we move into design. During this phase, we detail each component and add any necessary implementation classes to our application. Also, we apply the principles and design patterns discussed throughout this book to create a more robust architecture.

To effectively manage ASP.NET applications, administrators need runtime information about the system that is a reliable indicator of the health of the system. More important, this information should be easily consumable using standard tools and techniques. Table 12-5 details the events exposed by the ASP.NET health monitoring facility. The events are registered in the machine.config file.
