| Description | NLB Cluster %2 %1: Windows 2000 or NT 4.0 host(s) are participating in this cluster. Consult the relevant NLB documentation concerning the potential limitations of operating a mixed cluster. %3 %4 |
| Event Information | According to Microsoft: EXPLANATION: Certain features of Network Load Balancing (NLB) are not designed to work in a mixed cluster, that is, in a cluster with hosts running a product in the Windows Server 2003 family along with hosts running Windows 2000 or Windows NT 4.0. These features include virtual clusters, bidirectional affinity, and IPSec load balancing (such as VPN). USER ACTION: These features can be used if the cluster contains only hosts running a product in the Windows Server 2003 family. If you require any of these features, remove all hosts running Windows 2000 and Windows NT 4.0 from the cluster. |
