Active Directory Written Assignment Active Directory Multi – Master Design The Acme Widget Technical School has four campuses: one main campus and three branch campuses. All campuses currently have a child domain off the main domain, located at the main campus in Wiley, Minnesota. The main campus has approximately 125 employees and 2,000 students, while each branch campus has approximately 50 to 75 employees and 1,200 students. The main campus is called Wiley, the other campuses are Ethelbert, Freling, and Jones. Using the information from this scenario, answer the following questions: 1. How many and what type of domain controllers do you recommend for each campus? How would you justify this recommendation? 2. How many global catalog servers do you recommend for the campus? How would you implement and configure these global catalog servers? 3. Explain the steps for determining the placement of the FSMO roles for the Acme Widget Technical School. How are these roles determined, implemented, maintained, and monitored? 4. As a System administrator, detail some best practices as well as errors that can occur from improper setup and implementation of global catalogs or FSMO roles.

The design and deployment of Active Directory (AD) within a multi-campus educational institution like Acme Widget Technical School require meticulous planning and strategic implementation to ensure efficiency, fault tolerance, and scalability. The key aspects involve determining appropriate domain controller (DC) configurations, global catalog (GC) server deployment, and the proper placement and management of Flexible Single Master Operations (FSMO) roles. Each of these components plays a critical role in maintaining a resilient and responsive Active Directory infrastructure that supports the school's operational needs across multiple geographically dispersed campuses.

Domain Controller Deployment Strategy

For each campus—main and branch campuses—it's essential to balance the number and type of domain controllers to optimize authentication, authorization, and directory services, while also considering redundancy and disaster recovery. At the main campus in Wiley, with approximately 125 employees and 2,000 students, deploying at least two or three domain controllers is recommended. These should include a combination of Standard Read-Write Domain Controllers and, if necessary, Read-Only Domain Controllers (RODCs). The primary DC should host the Schema, Configuration, and Application directory partitions, while secondary DCs ensure fault tolerance and load balancing.

Branch campuses with fewer users—about 50 to 75 employees and 1,200 students—should have a minimum of two domain controllers, ideally one stationed locally to facilitate authentication and directory services, and a second at the main site or in a geographically strategic location for redundancy. Given the smaller size, an RODC could be advantageous in branch locations to enhance security, especially if the sites are less physically secure. Justification for these recommendations revolves around reducing authentication latency for local users, preventing single points of failure, and ensuring quick recovery in case of hardware or network failures.

Global Catalog Server Recommendations

Global Catalog (GC) servers are vital for forest-wide searches, universal group membership, and logon processes. In this multi-campus scenario, each campus should have at least one GC server, with additional GCs deployed in larger campuses like Wiley to handle increased query loads and ensure high availability. Specifically, deploying a minimum of one GC in each campus, and considering two in Wiley, enables faster and more reliable search and authentication operations.

Implementation involves designating the appropriate domain controllers as GCs during setup, and later verifying their GC role status through Active Directory Sites and Services. Proper configuration includes ensuring that the GCs are well-connected in Active Directory Sites and that replication occurs efficiently across sites. To implement this, the IT team should configure replication links with optimal schedules, and monitor replication health regularly to avoid inconsistencies or outdated directory information.

FSMO Role Placement and Management

FSMO roles are crucial for the health and stability of Active Directory. There are five FSMO roles: Schema Master, Domain Naming Master, Infrastructure Master, Relative ID (RID) Master, and PDC Emulator. The placement of these roles should consider the network topology and administrative convenience.

Typically, the Schema Master and Domain Naming Master roles are assigned at the forest level and should be placed on robust, reliable domain controllers—preferably in the main campus. The RID Master and PDC Emulator roles are usually hosted on domain controllers that have high availability and are centrally located for administrative ease and performance. The Infrastructure Master role should be on a domain controller that is not also hosting FSMO roles for the same domain, if possible, to prevent replication conflicts.

Steps for determining placement include analyzing network latency, server reliability, and administrative convenience. Implementation involves transferring FSMO roles using the Active Directory Users and Computers console or command-line tools like 'ntdsutil' or PowerShell cmdlets. Maintenance involves regular monitoring of FSMO health through tools like Microsoft System Center or PowerShell scripts, and immediate action if any role holder becomes unavailable.

Best Practices and Common Errors

Best practices for managing global catalogs and FSMO roles include assigning roles according to best-fit criteria such as server performance and network topology, implementing redundancy, and performing regular health checks. For global catalogs, it’s advisable to avoid deploying too many GCs on a single site or on unreliable servers to prevent performance bottlenecks.

Common errors from improper setup include consolidating multiple FSMO roles on a single server without redundancy, which can lead to a single point of failure, or misconfiguring global catalog servers—such as enabling GCs on low-performance servers—leading to slow query responses. Additionally, neglecting to regularly monitor FSMO roles can result in replication issues or role holder unavailability, causing AD operations to fail or degrade.

Ensuring proper documentation, routine health checks, and implementing automated alerts for FSMO and GC health status are essential for maintaining AD stability. Proper training for administrators on role transfer procedures and disaster recovery plans further mitigates risks associated with misconfiguration and failures.

Conclusion

Designing an effective Active Directory infrastructure for a multi-campus educational institution involves strategic planning for domain controllers, global catalog servers, and FSMO roles. By deploying multiple domain controllers tailored to each campus's size, ensuring sufficient global catalog servers, and appropriately placing FSMO roles, schools like Acme Widget can maintain a secure, efficient, and resilient directory environment. Adhering to best practices and avoiding common pitfalls significantly contribute to the stability and scalability of the network infrastructure supporting academic and administrative functions across all campuses.
