You have been hired by Fixing Windows LLC as an Information Technology consultant to develop a technology proposal.

Fixing Windows LLC manufactures and distributes solar panels for the consumer market. Your task is to prepare a comprehensive proposal addressing their current infrastructure, concerns, and future growth plans, with a focus on implementing Windows Server 2016 solutions for their network architecture.

The company has three locations: Los Angeles, Dallas, and Houston, with main staff at Dallas and Houston. As demand for solar panels increases, rapid expansion is expected. Data security is a priority due to sensitive patents and trademarks.

Existing connectivity exists via WAN with ample bandwidth, and secure remote access for Los Angeles sales personnel to Houston is required. The proposal should include assumptions with noted considerations.

Topics to be covered include:

  • DNS and DHCP: Implementation, scope design, fault tolerance, reservations, IP Address Management (IPAM), IPv6 utilization, security, zone types, and namespace strategies.
  • File Services, Distributed File System (DFS), and BranchCache: Share security, quotas, File Server Resource Manager (FSRM) configuration, and DFS deployment.
  • Remote Services and Network Policy Server (NPS): Secure remote access solutions and user access policies.
  • Networking concepts: High-performance network solutions and Software-Defined Networking (SDN).

The solution should be detailed, including technical and business reasons for each choice, and incorporate at least one diagram. The document should be approximately 6 to 10 pages in length, double-spaced, with 1-inch margins, and using 12-point Times New Roman or 10-point Arial font. Proper APA in-text citations and references are required.

Introduction

In the rapidly evolving landscape of technological infrastructure, small to medium-sized enterprises such as Fixing Windows LLC must adopt robust, scalable, and secure network solutions. As a manufacturer and distributor of solar panels, their operational success depends heavily on efficient data management, secure remote connectivity, and scalable network architecture. This proposal outlines a comprehensive plan to implement Windows Server 2016-based solutions addressing DNS and DHCP services, file management, remote access, and advanced networking strategies to support the company's growth and security demands.

DNS and DHCP Implementation

The Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) are foundational to network communication. Proper implementation ensures efficient, reliable, and secure network operations. DHCP installation in this context should involve authorized servers that dynamically assign IP addresses within defined scopes, reducing administrative overhead and minimizing conflicts (Cobb, 2019). Authorization of DHCP servers in Active Directory ensures only trusted servers distribute IP addresses, essential for security.

Designing DHCP scopes involves defining appropriate address ranges for each site, considering future growth. For Los Angeles, Dallas, and Houston, scopes must accommodate current devices with sufficient headroom for expansion. Lease times should be balanced, perhaps set to 8 hours or 1 day, to minimize address exhaustion while reducing network churn during business hours (Microsoft, 2016). Multiple scopes per site can be used to segment network segments, but simplicity favors fewer scopes aligned with physical locations.

To enhance fault tolerance, implementing DHCP failover protocols—either load balancing or hot standby—is recommended (Khanna & Gupta, 2021). This provides redundancy, ensuring continuous IP address allocation if a DHCP server fails. Reservations for critical servers—such as DNS, file servers, or network equipment—must be made to ensure consistent addressing, simplifying management and access.

IP Address Management (IPAM) in Windows Server 2016 offers centralized control, monitoring, and auditing of IP address spaces. IPAM tools enable administrators to track address utilization, plan expansions, and secure DHCP and DNS servers (Microsoft, 2018). Integration with DNS enhances visibility and control over namespace health and integrity.

IPv6 deployment is crucial to future-proof the network. Dual-stack deployment—running IPv4 and IPv6 simultaneously—allows seamless transition, with IPv6 providing scalable addressing and improved security features (Ferguson, 2020). Policies for IPv6, including security configurations, should be established for internal and external communications.

DNS Security is paramount, given the importance of protecting the company’s patent and trademark data. DNSSEC (Domain Name System Security Extensions) should be enabled to safeguard against DNS spoofing and cache poisoning attacks (Provoost et al., 2019). For multiple sites, DNS name resolution can be handled via zone transfers—either zone transfers or stub zones—configured for each location. Implementing a split namespace with internal and external zones helps segregate public and private data, enhancing security and management efficiency.

The company's DNS namespace should be hierarchical, reflecting their organizational structure. A recommended structure is fixingwindows.com, with sub-zones for sites, such as la.fixingwindows.com, dallas.fixingwindows.com, and houston.fixingwindows.com. This approach facilitates management and security segmentation.

File Services, DFS, and BranchCache

File sharing must be secured via NTFS permissions and share permissions, ensuring only authorized personnel can access sensitive files like patents and trademarks (Microsoft, 2016). Implementing quotas and FSRM policies can prevent accidental overuse of storage resources, ensuring optimal performance and resource management.

DFS provides a unified namespace across multiple locations, improving access speed and fault tolerance. Configuring DFS Replication ensures data consistency between sites, vital for collaboration between Los Angeles, Dallas, and Houston (Yuan, 2019). DFS also supports load sharing, reducing bottlenecks and improving user experience.

BranchCache optimizes WAN bandwidth utilization by locally caching frequently accessed data. Configuring BranchCache on client computers enhances remote access efficiency, especially for users in Los Angeles accessing Houston servers (Microsoft, 2018). This reduces latency and improves productivity, critical in a geographically dispersed company like Fixing Windows LLC.

Remote Services and NPS

Secure remote access is essential for remote sales personnel in Los Angeles connecting to Houston. Implementing a Remote Access VPN using Windows Server 2016 with IPsec or SSL VPN protocols provides encrypted channels, maintaining confidentiality and integrity (Khanna & Gupta, 2021). Cloud-based solutions or DirectAccess may be considered for seamless access without user intervention.

Network Policy Server (NPS) centralizes authentication, authorization, and accounting (AAA), integrating with Active Directory to enforce security policies (Yuan, 2019). NPS supports RADIUS protocols, enabling secure remote access requests and ensuring only authorized users can connect. Configuring NPS policies to include multi-factor authentication adds an extra layer of security, particularly for remote access to sensitive data.

Other Networking Concepts

To support high-performance networking, implementing quality of service (QoS) policies prioritizes critical traffic, such as remote access or backup operations. Software-Defined Networking (SDN) allows centralized management of network resources, enabling dynamic adjustments and enhanced security (Ferguson, 2020). SDN enhances agility and simplifies infrastructure management, supporting rapid expansion and integration of new locations.

In conclusion, a comprehensive Windows Server 2016-based network design incorporating secure DHCP, DNS, file services, remote access, and advanced networking strategies will position Fixing Windows LLC for scalable growth, enhanced security, and operational efficiency. Additionally, industry best practices and Microsoft recommendations should be continuously reviewed and incorporated to adapt to emerging threats and technological innovations.
