What is a key factor to consider when placing FSMO servers in a network?

When placing Flexible Single Master Operation (FSMO) servers in a network, high network availability is a key factor to consider. FSMO roles are critical for the proper functioning of Active Directory, and if these servers become unavailable, it can lead to significant issues such as replication failures and authentication problems throughout the network.

High network availability ensures that the FSMO servers are reachable by all domain controllers and clients that rely on their functions. This includes services like schema management, domain naming, and the operations master roles that are essential for maintaining a healthy and responsive active directory environment. By placing FSMO servers in well-chosen network locations with robust connectivity, administrators can help prevent downtimes and ensure that essential directory services are consistently available.

Factors such as the physical security of the server environment, proximity to the Internet Service Provider (ISP), and accessibility for all users are important considerations for infrastructure but do not directly impact the specific accessibility and operational reliability of FSMO roles within the network itself. Thus, while these other aspects may play a role in overall infrastructure planning, high network availability is paramount for the stability and functionality of FSMO servers.
