SUMMARY
This step-by-step article describes how to perform basic Network Load Balancing procedures. When you use Network Load Balancing, you can spread incoming requests across as many as 32 servers. When you do so, you can expand enterprise-wide services, such as Web servers, Terminal Services, and streaming media servers, to ensure that the services respond quickly, even under heavy loads.

Network Load Balancing automatically detects when a server fails and quickly reassigns client traffic among the remaining servers. This safeguard helps you provide uninterrupted, continuous service for your critical business programs.
