Hosts in a Network Load Balancing (NLB) cluster are configured to load balance network traffic. Host configuration is set by using NLB Manager, and if it is not configured properly, the NLB cluster may not function correctly
Restart the NLB cluster
If Network Load Balancing (NLB) detects that there are duplicate subnets in the cluster, it may be due to network partitioning, which prevents NLB heartbeats of one or more hosts from reaching the other cluster hosts. You may need to restart the NLB cluster to resolve this issue.
To restart the NLB cluster:
Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
Type nlb.exe reload, which reloads the NLB driver's current parameters from the registry.
Type nlb.exe start, which starts cluster operations on the specified hosts.
You can also reload the configuration and restart the cluster node using the links below:
