Defining Management Strategies A successful management plan for network services includes strategies that permit detection of, and response to, changes in the network services The management strategies define policies, procedures, and processes that permit the network administrator to respond to, verify, and anticipate variations in the service In this section: • Explain that the highest priority in a management plan must be to detect and respond to critical events such as service or network failures The need to monitor design compliance and anticipate the need for design changes is a lower priority Point out that strategies for responses to service variations can be reactive, proactive, manual, or automatic • Emphasize that management strategies must define processes to respond to the service variations automatically, or provide notification to operations staff for manual responses • Point out that verifying compliance with the design specifications requires both the monitoring and testing of the services • Emphasize that requirements for the services infrastructure will change over time as needs for resources change Operations staff can use collected information about the consumption of resources to anticipate the need for changes to the network design • Point out that the management plan must include processes to provide feedback and control of the network services infrastructure The processes must be designed to obtain the current status of the services, verify service compliance, and predict trends
Identifying Management Processes The management plan must include processes to provide feedback and control of the network services infrastructure The processes must be designed to obtain the current status of the services, verify compliance of the service operation, and respond to service variations Emphasize that any plan to monitor and respond to service variations is often part of a larger management system, such as Microsoft Systems Management Server, or third-party management solutions
Generating Information on the Status of the Services Emphasize that obtaining the operational status of a service requires information about individual service providers and network conditions, and verification that client requests receive appropriate responses In this section: • Emphasize that the collection of status information for analysis is critical to the process of monitoring the individual services and the overall network • Point out that command-line network tools and utilities can be used to test and analyze service and network operation and variation Explain that these tools and utilities can be used interactively, or their output stored in files for later analysis Module 11: Windows 2000 Network Services Management v • Explain that System Monitor, which is found within the Performance console allows you to obtain real-time data and collect logs • Make sure students understand the illustration, scenario description, and directions for the Discussion Direct them to read through the scenario and answer the questions Be prepared to clarify if necessary Lead a class discussion on the students’ responses • Emphasize that Simple Network Management Protocol (SNMP) can be used to both derive the status of hosts and control hosts in a Transmission Control Protocol/Internet Protocol (TCP/IP) network Point out that in a Windows 2000 network, SNMP is an optional component Emphasize that SNMP may be required to support services if the infrastructure has devices that are already managed and configured by using SNMP • Emphasize that Event logs are useful to calculate uptime based on service stop/starts, and to analyze errors and status changes Point out that the Event Log service starts automatically when you start Windows 2000 • Emphasize that acquiring the necessary status information requires the automated accumulation of logs, or the running of command-line utilities and programs Discuss the use of scripts and programs to provide scheduled automation • Emphasize that Windows Management Instrumentation (WMI) provides a single point of integration through which status information from many sources within a computer can be accessed Mention the sample scripts on the Student CD
Analyzing the Collected Data The status of the network services can be generated from real-time data, accumulated logs, and calculated result sets The analysis processes, either manual or automatic, draw on the collected status information to create a final result set This result set can then be used to respond to service variations
Selecting Response Strategies Emphasize that the time taken to return a service to full operation is a function of the time taken to detect and respond to the failure, and the time to repair Point out that minimizing the time taken to detect and respond to service variations, or to provide automated responses to service variations, can reduce the impact of failures and variations Module 11: Windows 2000 Network Services Management Overview Slide Objective To provide an overview of the module topics and objectives Lead-in In this module, you will evaluate and develop the management strategies required to manage a Windows 2000 networking services infrastructure

Selecting Response Strategies An essential component of a Microsoft® Windows® 2000 networking services infrastructure design is the management of the network services An effective management plan for network services can ensure that the functionality, security, availability, and performance of the network services, and the network, continue to meet the specifications of your infrastructure design At the end of this module, you will be able to:
Define strategies for managing the network services
Identify the processes used to execute a management plan
Select the appropriate methods to generate information about the status of the services
Select the appropriate methods to analyze collected data
Select appropriate response strategies Module 11: Windows 2000 Network Services Management
Defining Management Strategies Slide Objective Management Strategies To introduce management strategies used for a network services management plan Monitor All DNS Activity Management Plan for DNS Lead-in Responding Respondingto toService ServiceVariations Variations Your management strategies must define processes and procedures for detection, notification, and response to both critical and noncritical variations in network services Policies, Procedures, Processes Verifying VerifyingCompliance Compliancewith withDesign Design Policies, Procedures, Processes Anticipating AnticipatingChanges Changesto toaaDesign Design Policies, Procedures, Processes A management plan for network services is generated from strategies and permits detection of, and response to, changes in the network services Your management plan defines policies, procedures, and processes that permit you to respond to, verify, and anticipate variations in the service The highest priority in your management plan must be to detect and respond to critical events such as service or network failures At a lower priority, you must monitor design compliance and anticipate the need for design changes The strategies defining your management plan can specify reactive, proactive, manual, or automatic responses to service variations The management plan for network services is only one component of a larger network management plan The larger plan manages the network and applications that are supported in the organization You must give consideration to how the services management plan integrates with any larger network management plan A services management plan includes strategies for:
Responding to service variations as they occur
Verifying that current operations are compliant with the design specifications
Anticipating the need for changes to the network services design Management strategies must include processes and procedures used to continuously acquire the current status, analyze the collected data, and specify appropriate responses Module 11: Windows 2000 Network Services Management Responding to Service Variations Slide Objective To describe typical service variations that require immediate detection and response strategies Lead-in Your management plan must determine which service variations require immediate detection, along with the required responses to these variations Ask students to give examples of services and threshold values that are critical in their organizations
Services and Servers Unavailable
Client Requests Not Resolved
Threshold Values Exceeded
Calculated Values Outside Specification You must detect network service variations, such as the failure of a service, and respond appropriately to restore operation Your strategies must define processes to respond to the service variations automatically, or provide notification to operations staff for manual responses Typically, immediate detection, notification, and responses are required when:
Services or servers are unavailable
Client requests for services fail
Threshold values are exceeded
Calculated values are outside the specifications Wherever possible, an effective management plan defines processes to detect and respond to service variations before failure occurs Immediate notifications of service variations are required when operations staff must make the response If your strategies include processes to automate responses to service variations, these processes must also include notifications to operations staff of automated system responses that have occurred Module 11: Windows 2000 Network Services Management Verifying Compliance with the Design Slide Objective To describe how to ensure that functionality, security, availability, and performance are within the design specifications
Manual Testing
Scheduled Audits, Availability, and Redundancy Tests Lead-in
Monitoring To verify compliance with the design specifications, you must include both the monitoring and testing of the services
Service Uptime
Service Performance
Service-to-Service Interaction the The design specifications for an existing network services infrastructure provide the baseline against which to test compliance If the specifications are exceeded in operation, the services might no longer provide the required functionality, security, availability, or performance The specifications in a conservative design are selected with sufficient tolerance so that exceeding them does not cause immediate failure You can design your management plan to verify compliance with the design specifications either manually or automatically To verify that services are operating within the required specifications, it may be necessary to analyze both threshold values and accumulated data Manual Testing You cannot verify some aspects of a design, such as the testing of server redundancy, by using automatically collected data These design aspects require the definition of the appropriate manual processes and procedures to ensure that the services are compliant Scheduled Audits, Availability, and Redundancy Tests The security and access permissions for a service are often modified over time You can conduct regular audits to ascertain compliance with security, and access design specifications If the service infrastructure consists of multiple servers providing redundancy and load balancing, tests will confirm compliance with the design specifications Your compliance testing procedures can specify that servers or services be stopped to test the response of either automated or manual reconfiguration procedures ... iv Module 11: Windows 2000 Network Services Management Module Strategy Use the following strategy to present this module
