Windows Server 2008 Microsoft MCTS 70-643: Self-Paced Configuration and Deployment Guide

Microsoft Exam 70-643 Configuring Windows Server 2008 Applications Infrastructure focuses extensively on deploying servers using structured, automated methods that enhance reliability, consistency, and performance. Deploying servers is more than an installation task; it is a strategic operation that sets the foundation for the enterprise computing environment. In Windows Server 2008, deployment is handled through Windows Deployment Services, which allows for centralized, network-based installation of operating systems without the need for physical media or direct interaction at each machine. This method not only saves time and resources but also ensures a uniform server configuration across the organization.

Windows Deployment Services operates by hosting boot and install images that can be transmitted over the network using the Pre-Boot Execution Environment protocol. When a computer configured for PXE boot starts, it communicates with the WDS server, downloads a boot image, and initiates the setup process. Administrators can create and manage these images centrally, ensuring that each deployed system adheres to the organization’s configuration and compliance policies. WDS thus provides a repeatable, scalable deployment model suitable for environments ranging from small departments to enterprise data centers.

Setting up Windows Deployment Services begins with preparing the infrastructure. The WDS server must be part of an Active Directory domain, and essential network services such as DNS and DHCP must be available and properly configured. DNS provides name resolution during deployment operations, while DHCP assigns IP addresses to PXE clients. Once these components are in place, the administrator adds the Windows Deployment Services role using Server Manager, configures the image store path, and defines how the server responds to client requests. The next step involves adding boot and install images, which can be sourced directly from Windows Server 2008 installation media.

Administrators often build a reference computer that represents a standard system configuration, including operating system updates, role configurations, and installed applications. This reference system is then captured as an image using WDS tools and stored on the deployment server. The captured image can be redeployed repeatedly, ensuring identical environments on multiple servers. To further reduce manual intervention, administrators can create answer files that provide configuration details such as language settings, time zones, and licensing information. These files automate the installation process by supplying the required responses, enabling fully unattended installations that complete without user input.

Automation is central to enterprise deployment. Unattended installations through answer files ensure consistent configurations, while pre-installation and post-installation scripts allow administrators to apply additional settings or software automatically. WDS supports multicast transmission, allowing a single image to be deployed simultaneously to multiple machines. This minimizes bandwidth consumption compared to individual unicast transfers and accelerates deployment for large groups of servers. Administrators can control multicast sessions based on client readiness or specific scheduling windows, optimizing the process according to organizational needs.

Security during deployment is maintained through pre-staged client configuration in Active Directory. Each computer object can be linked to a specific image, ensuring that only authorized systems receive the operating system. This protects corporate images from unauthorized use. Event logs generated by Windows Deployment Services record all deployment activity, providing an audit trail that administrators can monitor for failed installations, errors, and potential security incidents. Maintaining proper logging and reviewing these reports helps identify deployment issues early and preserve image integrity.

Configuring Microsoft Windows Activation

Once a server has been deployed, activation ensures that the installation complies with Microsoft’s licensing requirements. Windows Server 2008 supports two activation mechanisms: Multiple Activation Key and Key Management Service. The Multiple Activation Key model is ideal for smaller networks where each server directly contacts Microsoft’s activation servers to validate its license. In contrast, the Key Management Service is designed for larger organizations and allows servers to activate locally within the network by communicating with a designated KMS host. This host system maintains an internal activation count and periodically renews activations for all connected clients.

Configuring the KMS host involves installing the host key, activating it once with Microsoft, and ensuring that the service publishes the appropriate DNS record so that other systems can automatically discover it. Clients then contact the KMS host to complete activation, reducing manual input and maintaining centralized license control. Administrators can verify activation status using built-in tools such as the Software Licensing Management utility or the graphical System Properties interface. By implementing a KMS infrastructure, organizations simplify activation management and ensure continuous compliance even when systems are reimaged or redeployed.

Configuring Windows Server Hyper-V and Virtual Machines

Virtualization is a cornerstone of modern infrastructure management, and Windows Server 2008 introduces Hyper-V as a built-in hypervisor that supports the creation and administration of virtual machines. Hyper-V allows multiple isolated operating systems to run concurrently on a single physical host, improving hardware utilization and enabling flexible resource allocation. Installing the Hyper-V role through Server Manager requires hardware that supports virtualization extensions and Data Execution Prevention. Once enabled, administrators use the Hyper-V Manager to create, configure, and monitor virtual machines.

Each virtual machine is provisioned with configurable virtual hardware, including CPU allocation, memory, network interfaces, and virtual disks. Virtual networking is handled through virtual switches that provide connectivity between virtual machines, the host system, and external networks. External switches bridge traffic to the physical network, internal switches facilitate communication between virtual machines and the host, and private switches isolate virtual machines from all external communication. Storage for virtual machines is defined through virtual hard disks, which can be fixed-size for performance, dynamically expanding for flexibility, or differencing to save storage space by linking multiple virtual machines to a base image.

Hyper-V integrates closely with Windows Deployment Services, allowing administrators to automate the provisioning of virtual machines using network-based installation images. A reference virtual machine can be generalized with the System Preparation Tool, captured, and then redeployed to multiple hosts. This approach standardizes virtual environments across development, testing, and production systems while minimizing manual configuration time. Integration with management tools such as System Center Virtual Machine Manager further enhances control by providing centralized oversight for multiple Hyper-V hosts.

Configuring High Availability

High availability ensures that essential services remain accessible even during hardware or software failures. Windows Server 2008 implements this through failover clustering, which allows multiple servers to operate as a unified system where one node can take over the workload of another in the event of failure. To configure failover clustering, administrators use the Failover Cluster Manager, validate hardware compatibility, and connect each node to shared storage accessible by all cluster members. Validation tests verify network configuration, disk accessibility, and driver compatibility to confirm readiness for cluster creation.

Once the cluster is established, services and applications can be configured as clustered resources. The cluster continuously monitors node health and automatically transfers resources to another node if one becomes unavailable. This capability minimizes downtime and provides continuous service to users and applications. Windows Server 2008 also supports Cluster Shared Volumes, enabling multiple nodes to access the same virtual hard disk concurrently. This feature is particularly beneficial for virtualized environments because it allows for live migration of virtual machines between cluster nodes without service interruption.

Administrators can fine-tune failover policies to define resource dependencies, startup priorities, and failback behavior. For example, a database service might depend on storage availability and must therefore start only after its associated disk resources are online. These configurations ensure orderly recovery and stable cluster performance. Monitoring tools integrated within the Failover Cluster Manager and Event Viewer provide insight into resource health, enabling proactive management of cluster operations.

Configuring Storage

Efficient storage configuration supports both performance and reliability within deployed infrastructures. Windows Server 2008 provides a range of tools to manage disks and volumes, including the Disk Management console and DiskPart command-line utility. Administrators can create basic or dynamic disks, partition drives, and assign volumes as needed to meet system requirements. Dynamic disks support advanced configurations such as spanning, striping, mirroring, and RAID-5 arrays. These options help balance performance and fault tolerance, ensuring that critical data remains accessible even in the event of hardware failure.

For larger environments, centralized storage solutions such as Storage Area Networks or iSCSI targets provide scalable and resilient data access. Windows Server 2008 supports iSCSI initiators that allow servers to connect to remote storage devices over TCP/IP networks as though they were local disks. Administrators can also implement shadow copies to create point-in-time snapshots of files, protecting data against accidental deletion or corruption. The Distributed File System further enhances reliability by replicating and synchronizing data across multiple locations, ensuring availability and consistency throughout the enterprise.

Configuring Remote Desktop Services

Windows Server 2008 includes multiple components within Remote Desktop Services that can be configured to create a seamless and efficient remote access environment.

Configuring Remote Desktop Session Host forms the foundation of Remote Desktop Services deployment. The Session Host server provides the environment where user sessions are executed. When users connect remotely, their input and display data are transmitted over the Remote Desktop Protocol, while applications run on the Session Host server itself. Administrators configure the Remote Desktop Session Host role through Server Manager, enabling settings that define session limits, timeouts, and resource allocation. Proper configuration ensures balanced performance, prevents resource exhaustion, and provides a responsive experience for users accessing hosted applications or desktops.

Remote Desktop licensing is an essential component of Remote Desktop Services. It ensures that all users or devices accessing the system are properly licensed according to Microsoft’s terms. When the Remote Desktop Licensing role is installed, administrators activate a license server and install the appropriate license packs. The licensing server issues and tracks client access licenses as users connect. Two licensing modes are available: per-user and per-device. In per-user mode, each user has access from multiple devices, whereas in per-device mode, each unique device connecting to the Session Host requires its own license. Licensing must be carefully managed to ensure compliance and continuous service availability.

Once the Session Host and Licensing roles are established, the next step involves configuring the Remote Desktop Connection Broker. The Connection Broker provides session load balancing and reconnection capabilities across multiple Session Host servers. It keeps track of active sessions and redirects returning users to their existing sessions rather than creating new ones. This ensures that users can reconnect seamlessly after network interruptions without losing their session state. To configure the Connection Broker, administrators integrate it with Session Host servers, define server groups, and specify load-balancing parameters that distribute incoming connections evenly. This configuration provides scalability and improves performance in environments where many users connect concurrently.

Remote Desktop Gateway further enhances access by allowing secure connections from external networks without requiring a traditional VPN. The Gateway encapsulates Remote Desktop traffic within HTTPS tunnels, which pass through standard firewalls without special configuration. Administrators install the Remote Desktop Gateway role, configure SSL certificates, and define policies controlling who can connect, from where, and to which internal resources. Connection Authorization Policies and Resource Authorization Policies govern authentication and authorization processes, ensuring that only verified users access permitted systems. Integration with Network Policy Server enables centralized enforcement of these security rules.

Remote Desktop Web Access complements the Gateway by providing a web-based interface for users to launch remote applications and desktops directly from a browser. The Web Access role integrates with Active Directory and the Connection Broker to display available resources dynamically. Administrators can customize the web portal to reflect organizational branding and specify which applications appear for different user groups. The combination of Web Access and Gateway provides a unified and secure method for remote connectivity, eliminating the need for complex client configurations.

Another critical feature within Remote Desktop Services is RemoteApp. RemoteApp allows administrators to publish individual applications rather than entire desktop sessions. This gives users the experience of running local applications while the actual processing occurs on the server. Administrators create and publish RemoteApp programs using the RemoteApp Manager, define parameters for each application, and distribute .rdp or Windows Installer packages to users. When launched, the application appears in a window on the local desktop, integrated with the client’s taskbar and start menu, yet operating entirely on the Remote Desktop Session Host. RemoteApp simplifies software deployment, centralizes updates, and enhances performance by reducing local resource usage.

Monitoring and managing Remote Desktop resources is crucial for maintaining stability and performance. Windows Server 2008 includes tools such as the Remote Desktop Services Manager, which allows administrators to view active sessions, send messages, disconnect users, or log them off as needed. Administrators can monitor CPU, memory, and bandwidth usage per session to detect bottlenecks and optimize resource allocation.

Administrators install the Gateway role through Server Manager and configure a valid SSL certificate from a trusted certificate authority. This certificate secures communications between external clients and the Gateway server.

Policy configuration within the Gateway determines access permissions. Connection Authorization Policies define which users or groups are allowed to connect, while Resource Authorization Policies specify which internal computers or applications they can access. These policies integrate with Active Directory, allowing centralized authentication and the application of granular access controls. Integration with Network Policy Server enhances flexibility by allowing administrators to define conditions, such as client operating system version or health complianc,e before permitting access.

Administrators can further protect the environment by enabling logging and auditing for all connections through the Gateway Manager. This data provides insight into user activity, connection times, and access patterns, supporting both troubleshooting and compliance efforts. To ensure performance, the Gateway can be load-balanced across multiple servers, distributing client connections evenly and providing redundancy in case of hardware failure.

Configuring Remote Desktop Connection Broker

The Remote Desktop Connection Broker maintains session information for all connected users in environments with multiple Session Host servers. Its primary role is to ensure that users who disconnect are reconnected to their existing sessions rather than starting new ones. This is especially useful in load-balanced scenarios, where incoming connections may be distributed across different servers. The Connection Broker keeps track of each user session and its associated server, allowing seamless reconnection regardless of which server the client contacts initially.

Configuration begins by installing the Connection Broker role and adding participating Session Host servers to the broker farm. Administrators must ensure that all servers are members of the same Active Directory domain and that the broker is accessible to clients. DNS round-robin or network load-balancing solutions can distribute initial connection requests among servers, while the broker directs reconnections accurately. Load balancing is optimized through policies that consider server load, session count, and resource utilization, ensuring even distribution of workloads.

Monitoring within the Connection Broker provides detailed reports on user sessions, reconnections, and load distribution, helping administrators evaluate system performance and make necessary adjustments. This ensures efficient resource usage and consistent user experiences across multiple hosts.
