  1. Windows Network Load Balancing (NLB) allows multiple Windows Servers to operate as a single virtual cluster, distributing incoming TCP/IP traffic evenly across hosts. This improves availability, scalability, and redundancy for critical services like IIS web servers, VPN gateways, and SQL reporting servers.

    Key Benefits include:

    • High availability: Automatic detection of failed hosts and redistribution of load within ~10 seconds.

    • Scalability: Add up to 32 hosts dynamically without downtime.

    • Manageability: Centralized control via NLB Manager or PowerShell cmdlets.

    Installing NLB via PowerShell Run this on each server that will join the cluster:

    Install-WindowsFeature NLB -IncludeManagementTools

    No reboot is required.
