SYSTEM MANAGEMENT SERVER
System Management Server (SMS) 2.0 and 2003 are useful add-on products for system administration. It is one of three primary auxiliary management tools; the others are Application Center 2000 and Microsoft Operations Manager (described in the next section).SMS is not part of the core Windows Server 2003 operating system, but some of its features can be very valuable in deployment and administration. Since SMS is an optional component, we provide a review of its key features rather than in-depth "how to" instructions. Despite its summary treatment here, however, SMS should be considered seriously for relatively large and complex enterprises.The five primary SMS features that can be used effectively in the administration of a Windows Server 2003 enterprise are:
Software and hardware inventory gathering and management
Software installation and distribution
Remote tools
Software metering
Network diagnostics
System Management Server 2.0 depends on Microsoft SQL Server 6.5 or 7.0 (or later) to store and manage SMS data. SQL Server is available as an independent database. Whether you license SMS independently or as part of the BackOffice suite, you must still calculate the use and cost of installing a local or remote SQL Server.System Management Server 2.0 supports administrative snap-ins to the Microsoft Management Console (MMC). SMS service pack 2 must be employed.
Software and Hardware Inventory
In Chapter 4 we underscored the importance of inventorying hardware and software as part of Server planning and deployment. SMS can streamline this necessary step by automatically collecting software and hardware data and creating a dynamic inventory database. Moreover, it permits filtering of information so that both global and very granular inventories can be maintained. Through the use of SMS, specific software versions can be obtained, which permits rapid evaluation of enterprise upgrade status. For example, the hardware inventory evaluates a system's components according to processor manufacturer, revision levels, and type.
Software Installation and Distribution
The problems associated with centralized software installation and distribution to a remote computer or groups of computers are greatly reduced by SMS because it automates and schedules installation for minimal impact on the end user. Through the use of SMS's software inventory features, it is possible to create what is known as collector groups. The system administrator should use these to gather systems with the same processor, user group, or existing software, and then, with this information in hand, apply specific software upgrades to define collector groups automatically. In this way, the inventory database is automatically updated.The SMS installer creates application-specific scripts to support this distribution The SMS installer creates application-specific scripts to support this distribution process. Physical distribution can be direct to the client disk or through the posting of the application to a Web or FTP site.
Remote Administrative Tools
Using SMS, the system administrator can gain access to a remote client system and display the contents locally. By seeing exactly what is displayed on the user's end, the administrator can troubleshoot system problems. Moreover, an interactive chat feature permits the administrator and end user to discuss problems on screen. Client computer commands and applications can be executed with Remote Execute. Remote Boot restarts the client computer.
Software Metering
The software-monitoring feature is used primarily to manage licenses and identify unsupported or unregistered packages. Monitoring concurrent software usage throughout an enterprise makes it easy to determine if too many or too few licenses exist for a given software title. The monitoring tool is set to access and restrict use of applications by the individual user, user group, computer, quota, or license. Mobile users can also use it to check software licenses when not connected to the network.
Network Diagnostics
SMS extends Windows Server 2003 network administrative and monitoring with its network discover and trace functions. These functions provide a framework of the network structure in a dynamic enterprise environment by discovering and tracing network devices. By using SMS, a network topology map can be easily generated.The Network Monitor is used primarily to troubleshoot a network by capturing packets or frames and "sniffing" them. The information revealed is then displayed and filtered. The system administrator can edit network packets (see Figure 17.9).
