Event ID 4096 — NLB Host Configuration
Applies To: Windows Server 2008 R2
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.
|Product:||Windows Operating System|
|Message:||Configuration completed. Microsoft Cluster Service is also installed on this machine, and this may prevent the proper operation of both.|
Separate MSCS and NLB clusters
You cannot install Network Load Balancing (NLB) on a computer that is already a member of a failover cluster. This can interfere with a failover cluster's use of network adapters, and therefore, this configuration is not supported.
You must use a separate group of computers for Failover Clustering and for NLB Clustering.
When you are using nlb.exe, you must be a member of the Administrators group on the host that you are configuring, or you must have been delegated the appropriate authority. If you are configuring a cluster or host by running nlb.exe from a computer that is not part of the cluster, you do not have to be a member of the Administrators group on that computer.
To verify that all Network Load Balancing (NLB) hosts are in the converged state:
- 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 query, which displays the current cluster state and the list of host priorities for the current hosts of the cluster.
- Confirm that all hosts display converged as their current state.
