SourceNLB
DescriptionNLB Cluster %2 %1: NLB was unable to open the NLB public connection callback object and will therefore be unable to track connections. %3 %4
Event InformationError Message Explanation: Network Load Balancing (NLB) tracks TCP connections to ensure affinity to the host servicing the connection. In a Microsoft Internet Security and Acceleration Server (ISA Server)/NLB deployment, if NLB cannot open a communication channel with the firewall engine, it cannot guarantee, under certain conditions, that a given TCP connection is serviced by the same host for its duration.
USER ACTION: This communication medium with the firewall engine is required for ISA Server/NLB deployments. Check the ISA Server installation to verify that it is correctly configured, and then try restarting the host.
